Heat of Fusion How much thermal energy is needed change 50.0 g of ice at -20.0°C to water at 10.0°C?

Answers

Answer 1

We should divide the problem into 3 separate processes.

1) Bring the temperature of the ice from [tex]-20.0^{\circ}C[/tex] to its melting point ([tex]0^{\circ}C[/tex]): the amount of heat needed in this process is
[tex]Q_1=mC_s \Delta T[/tex]
where
[tex]m=50.0 g[/tex] is the mass of the ice
[tex]C_s = 2.108 J/g^{\circ}C[/tex] is the specific heat capacity of ice
[tex]\Delta T=0^{\circ}C-(-20^{\circ}C)=20^{\circ}C[/tex] is the increase of temperature

Plugging numbers into the equation, we find
[tex]Q_1 = (50.0 g)(2.108 J/g^{\circ}C)(20^{\circ}C)=2108 J[/tex]

2) Fusion of ice
When the ice is at melting point, we need to add a certain amount of heat in order to melt it, and this amount of it is given by:
[tex]Q_2 = mL_f[/tex]
where
[tex]m=50.0 g[/tex] is the mass of ice
[tex]L_f = 334 J/g[/tex] is the latent heat of fusion of ice

Plugging numbers into the equation, we find
[tex]Q_2 = mL_f = (50.0g)(334 J/g)=16700 J[/tex]
During this phase transition, the temperature of the ice/water does not change.

3) Bring the temperature of the water from [tex]0^{\circ}C [/tex] to [tex]10^{\circ}C[/tex]

The amount of heat needed for this process is
[tex]Q_3 = mC_s \Delta T[/tex]
where
[tex]m=50.0 g[/tex] is the mass of water
[tex]C_s = 4.187 J/g^{\circ}C[/tex] is the specific heat capacity of water
[tex]\Delta T=10^{\circ}C-0^{\circ}C=10^{\circ}C[/tex] is the increase of temperature

Plugging numbers into the equation, we find
[tex]Q_3 = (50.0 g)(4.187 J/g^{\circ}C)(10.0^{\circ}C)=2094 J[/tex]

--> therefore, the total energy needed for the whole process is:
[tex]Q=Q_1+Q_2+Q_3=2108 J+16700 J+2094 J=20902 J=20.9 kJ[/tex]

Without the skeletal system, the body could not fight off infection. Please select the best answer from the choices provided. T F

Answers

Answer:

TRUE

Explanation:

got it right on edge 2022.

The statement Without the skeletal system, the body could not fight off infection is false.

The skeletal system provides support, protection, and movement for the body, and it also plays a role in the production of blood cells through bone marrow. However, the primary function of fighting off infections is carried out by the immune system, which includes the lymphatic system, the spleen, the thymus, and bone marrow, among other components. While bone marrow is part of the skeletal system and is crucial for producing immune cells, the skeletal system itself is not the sole or primary defense against infection. Therefore, the statement is incorrect because it overstates the role of the skeletal system in immune function. The immune system, not the skeletal system, is specialized to fight off infections

which statement best describes Gay-Lassac’s law

Answers

Gay-Lussac’s Law is a component of the Ideal Gas Law that deals with the relationship between the change of pressure and temperature while holding volume constant. The equation looks like this:

P1 P2
— = —
T1 T2

where P1 and T1 represent the pressure and temperature before the change, and P2 and T2 represent the pressure and temperature after.

Final answer:

Gay-Lussac's law states that the pressure of a given amount of gas is directly proportional to its temperature on the Kelvin scale, provided the volume is constant. This was initially discovered by Guillaume Amontons and later refined by Joseph Louis Gay-Lussac. The mathematical representation is P proportional to T, P = constant × T or P = kx T.

Explanation:

The best description of Gay-Lussac's law is that it states that the pressure of a given amount of gas is directly proportional to its temperature on the Kelvin scale when the volume is held constant. Guillaume Amontons was the first to empirically establish this relationship between pressure and temperature of a gas around 1700, and Joseph Louis Gay-Lussac defined the relationship more accurately around 1800. This relationship is expressed mathematically as PxT or P = constant × T or P = kx T.

If a 100N weight sits in an express elevator what will be the weight when the elevator is traveling at a constant speed

Answers

This is a "trick" question.

If the elevator is traveling at constant speed, it means it is at rest. This means anything inside the elevator traveling at constant speed, weights the same as in an elevator not moving -also at rest-.

So the 100N weight's weight doesn't change in an elevator traveling at constant speed.

Final answer:

The weight of the 100N weight will remain the same when the elevator is travelling at a constant speed.

Explanation:

When the elevator is travelling at a constant speed, the weight of the 100N weight will remain the same. The weight of an object is the force exerted on it due to gravity, and this force does not change regardless of the elevator's speed or direction. So, the weight of the object will still be 100N.

you stretch a spring by a distance of 0.3 m. the spring has a spring constant of 440 n/m. when you release the spring, it snaps back. what is the kinetic energy of the springs as it reaches its natural length?

Answers

Answer:

19.8 J

Explanation:

According to the law of conservation of energy, the total mechanical energy of the spring (sum of kinetic energy and elastic potential energy) must be conserved:

[tex]K_i + U_i = K_f + U_f[/tex] (1)

where we have

[tex]K_i[/tex] is the initial kinetic energy of the spring, which is zero because the spring starts from rest (2)

[tex]U_i[/tex] is the elastic potential energy of the spring when it is fully stretched

[tex]K_f[/tex] is the kinetic energy of the spring when it reaches the natural length

[tex]U_f[/tex] is the elastic potential energy of the spring when it reaches its natural length, which is zero because the stretch in this case is zero (3)

[tex]U_i = \frac{1}{2}k(\Delta x_i)^2[/tex]

where

k = 440 N/m is the spring constant

[tex]\Delta x_i = 0.3 m[/tex] is the initial stretching of the spring

Substituting,

[tex]U_i = \frac{1}{2}(440)(0.3)^2=19.8 J[/tex]

And so using eq.(1) and keeping in mind (2) and (3) we find

[tex]K_f= U_i = 19.8 J[/tex]

What aspects of bone’s structure make it stronger than concrete? think about the engineering design of bone. use the terms tensile strength and compressional strength in your answer?

Answers

Bone's structure is optimized for strength due to its complex arrangement of organic and inorganic materials.

Tensile strength is a key factor: collagen fibres in bone resist pulling forces, making it flexible yet tough.

Compressional strength is achieved through the dense arrangement of mineralized hydroxyapatite crystals, providing resistance against crushing loads.

This combination of tensile and compressional strength allows bone to withstand bending, twisting, and impact. In contrast, concrete primarily relies on compressional strength, making it brittle and prone to fracture under tension.

Bone's intricate structure, with collagen providing flexibility and hydroxyapatite providing rigidity, makes it significantly stronger and more resilient than concrete in various mechanical scenarios.

Bones have a higher tensile and compressional strength than concrete due to their composite structure of collagen fibers and mineralized matrix, along with a complex microarchitecture designed to adapt to mechanical stresses. These aspects make bones robust and efficient weight-bearing structures.

The aspects of bone's structure that make it stronger than concrete are related to its complex microarchitecture and composite nature, which enable it to have a high tensile strength and compressional strength. Bones are formed from collagen, much like the steel rebar in concrete, and a mineralized matrix rich in calcium, which bears similarity to the concrete itself. However, the collagen provides flexibility and tensile strength, while the inorganic salts provide compressional strength, making bones robust and capable of adapting to mechanical stresses.

The ultimate strength of human bones, particularly in the femur, is impressive, with an ultimate compressive strength of 205 MPa and an ultimate tensile strength of 135 MPa. This strength is a result of bones being weight-bearing structures, designed to carry loads much like the columns in a building or fibrous structures like trees. The engineering design of bones takes into account different stresses on different parts of the body, which is why the structure of the femur can vary from thin sheets separated by marrow to cylindrical shapes filled with or without marrow.
The elastic modulus of bone also varies based on whether it is under tension or compression, highlighting the bone's capability to withstand different directional forces. Such properties make bones incredibly efficient at carrying weight and resisting different types of stresses without fracturing under normal circumstances.

Answers

There is a missing data in the text of the problem (found on internet):
"with force constant k=450N/m"

a) the maximum speed of the glider

The total mechanical energy of the mass-spring system is constant, and it is given by the sum of the potential and kinetic energy:
[tex]E=U+K= \frac{1}{2}kx^2 + \frac{1}{2} mv^2[/tex]
where
k is the spring constant
x is the displacement of the glider with respect to the spring equilibrium position
m is the glider mass
v is the speed of the glider at position x

When the glider crosses the equilibrium position, x=0 and the potential energy is zero, so the mechanical energy is just kinetic energy and the speed of the glider is maximum:
[tex]E=K_{max} = \frac{1}{2}mv_{max}^2 [/tex]
Vice-versa, when the glider is at maximum displacement (x=A, where A is the amplitude of the motion), its speed is zero (v=0), therefore the kinetic energy is zero and the mechanical energy is just potential energy:
[tex]E=U_{max}= \frac{1}{2}k A^2 [/tex]

Since the mechanical energy must be conserved, we can write
[tex] \frac{1}{2}mv_{max}^2 = \frac{1}{2}kA^2 [/tex]
from which we find the maximum speed
[tex]v_{max}= \sqrt{ \frac{kA^2}{m} }= \sqrt{ \frac{(450 N/m)(0.040 m)^2}{0.500 kg} }= 1.2 m/s[/tex]

b) the speed of the glider when it is at x= -0.015m

We can still use the conservation of energy to solve this part.
The total mechanical energy is:
[tex]E=K_{max}= \frac{1}{2}mv_{max}^2= 0.36 J[/tex]

At x=-0.015 m, there are both potential and kinetic energy. The potential energy is
[tex]U= \frac{1}{2}kx^2 = \frac{1}{2}(450 N/m)(-0.015 m)^2=0.05 J [/tex]
And since
[tex]E=U+K[/tex]
we find the kinetic energy when the glider is at this position:
[tex]K=E-U=0.36 J - 0.05 J = 0.31 J[/tex]
And then we can find the corresponding velocity:
[tex]K= \frac{1}{2}mv^2 [/tex]
[tex]v= \sqrt{ \frac{2K}{m} }= \sqrt{ \frac{2 \cdot 0.31 J}{0.500 kg} }=1.11 m/s [/tex]

c) the magnitude of the maximum acceleration of the glider;

For a simple harmonic motion, the magnitude of the maximum acceleration is given by
[tex]a_{max} = \omega^2 A[/tex]
where [tex]\omega= \sqrt{ \frac{k}{m} } [/tex] is the angular frequency, and A is the amplitude.
The angular frequency is:
[tex]\omega = \sqrt{ \frac{450 N/m}{0.500 kg} }=30 rad/s [/tex]
and so the maximum acceleration is
[tex]a_{max} = \omega^2 A = (30 rad/s)^2 (0.040 m) =36 m/s^2[/tex]

d) the acceleration of the glider at x= -0.015m

For a simple harmonic motion, the acceleration is given by
[tex]a(t)=\omega^2 x(t)[/tex]
where x(t) is the position of the mass-spring system. If we substitute x(t)=-0.015 m, we find
[tex]a=(30 rad/s)^2 (-0.015 m)=-13.5 m/s^2[/tex]

e) the total mechanical energy of the glider at any point in its motion.

we have already calculated it at point b), and it is given by
[tex]E=K_{max}= \frac{1}{2}mv_{max}^2= 0.36 J[/tex]

Final answer:

To compute the maximum speed, use the equation vmax = Aω. At x = 0, the speed is 0. The maximum acceleration is given by amax = Aω².

Explanation:

To compute the maximum speed of the glider, we can use the equation vmax = Aω, where A is the amplitude (0.040 m) and ω is the angular frequency. The angular frequency is given by ω = √(k/m), where k is the force constant (N/m) and m is the mass (kg). In this case, k = 80 N/m and m = 0.500 kg.

For part (b), the speed of the glider when it is at x = 0 (the equilibrium position) is 0. This is because the velocity is at a maximum when the glider passes through the equilibrium position, and at that point, it changes direction.

The maximum acceleration of the glider can be found using the equation amax = Aω². The magnitude of the maximum acceleration occurs at the position x = -A, so we can substitute -A for x in the equation. Finally, the acceleration of the glider at x = -A can be found by substituting this value into the equation a = -Aω².

p is the gas pressure
V its volume
n the number of moles
R the gas constant
T the absolute temperature

Before using this equation, we have to convert the temperature in Kelvin:

4. Air particles around the object begin to vibrate.

5. Energy transfers outward from air particle to air particle.

Answer: The order is 2,1,5,4,3

Explanation: Hope This helps.

The order in which events occur in the generation and transmission of a sound wave begins with an object vibrating, which transfers energy to air particles, leading to the vibration of surrounding air and the eventual transfer of energy from particle to particle, forming a sound wave.

Sound is produced and travels through a medium via a series of events that can be listed in sequential order:

Something causes an object to vibrate.

The object's energy transfers to the surrounding air particles.

Air particles around the object begin to vibrate.

Vibrating air particles bump into other air particles.

Energy transfers outward from air particle to air particle.

For example, when a tuning fork is struck, its tines vibrate and cause air molecules nearby to oscillate. These vibrations propagate outward as successive air molecules collide, similar to ripples in water when a stone is thrown. This movement of air molecules forms a sound wave, which can be detected by the ear as changes in air pressure and interpreted as sound.

Find the total translational kinetic energy of 1.5 l of oxygen gas held at a temperature of 0°c and a pressure of 0.8 atm.

Answers

The ideal gas law states that:
[tex]pV=nRT[/tex]
where
p is the gas pressure
V is its volume
n is the number of moles
R is the gas constant
T is the absolute temperature

However, this equation can be also rewritten as
[tex]PV= \frac{2}{3}NK [/tex] (1)
where
N is the number of molecules in the gas, and K is the average kinetic energy of the molecules. Therefore, NK represents the total kinetic translational energy of the gas.

For the gas in our problem,
[tex]p=0.8 atm = 8.08 \cdot 10^4 Pa[/tex]
[tex]V=1.5 L =1.5 \cdot 10^{-3} m^3[/tex]
So, the total translational kinetic energy of the gas is (using eq.(1) )
[tex]NK= \frac{3}{2}pV= \frac{3}{2}(8.08 \cdot 10^4 Pa)(1.5 \cdot 10^{-3} m^3)=181.8 J [/tex]

Final answer:

To calculate the total translational kinetic energy of 1.5 liters of oxygen gas at 0°C and 0.8 atm, use the ideal gas law to find the number of moles and then apply the translational kinetic energy equation (KEtrans = (3/2)nRT).

Explanation:

To find the total translational kinetic energy (KEtrans) of 1.5 liters of oxygen gas at 0°C (273 K) and 0.8 atm, we can use the ideal gas law and the equipartition theorem. The ideal gas law PV = nRT can give us the number of moles of oxygen gas when rearranged to n = PV/RT. Here, P is the pressure, V is the volume, R is the ideal gas constant, and T is the temperature.

Once the moles (n) are calculated, the translational kinetic energy per mole of a gas can be found using the equation KEtrans = (3/2)nRT, where n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin. By substituting the values into the equation, we can find the total translational kinetic energy of the gas sample.

What would you need to know to calculate the angular momentum of a man on a Ferris wheel?

Answers

The angular momentum calculated with respect to the axis of rotation of an object is given by:
[tex]L=mvr[/tex]
where m is the object's mass, v is its tangential speed, and r is its distance from the axis of rotation.

In case of a man on a Ferris wheel, we need to have these quantities in order to calculate his angular momentum. These quantities corresponds to:
- m, the mass of the man
- v, the tangential speed of the wheel at its edge
- r, the radius of the wheel

It is possible to calculate the angular momentum even if we don't know v, the tangential speed. In this case, we need to know at least the angular velocity [tex]\omega[/tex] (because from this relationship we can find the tangential speed: [tex]v=\omega r[/tex]) or the period of rotation of the wheel, T (because we can find the angular velocity from it: [tex]\omega= \frac{2 \pi}{T} [/tex]).

To calculate the angular momentum of a man on a Ferris wheel you need to know the mass distribution, radius, initial and final angular velocity, and angular acceleration of the system.

Angular momentum of a man on a Ferris wheel can be calculated using the formula:

Angular momentum = Moment of inertia x Angular velocity

To calculate this, you would need to know the mass distribution, radius, initial and final angular velocity, and angular acceleration of the system.
