Answer: gaseous
Explanation:
The major states of matter are solid, gaseous, liquid and plasma. However, there numerous others continued to be discovered such as Bose-Einstein condensate due to continuous research.
Solid state of matter usually have shape and volume which is a major physical characteristic of solids, liquid state of matter do not have shape but have volume however, the tend to occupy the shape of the container with respect to their volume in the container. Gaseous state of matter do not shape or volume but just occupy space in the container.

What is the total amount of energy required to melt 100 grams of ice at 0DC to liquid water at 0DC?
Answer: 301 kJ of energy
Explanation:
Compared to oceanic crust , continental crust is generally
Continental crust is typically thicker, more complex in its composition and predominantly made of granite compared to oceanic crust which is thinner, simpler and mainly composed of basalt. The continental crust covers 45% of earth's surface, whereas oceanic crust covers 55%. The continental crust, being thicker and more buoyant, is generally not subducted in plate tectonics unlike the oceanic crust.
Explanation:Compared to the oceanic crust, the continental crust is typically thicker and composed predominantly of different types of rocks. While oceanic crust is about 6 kilometers thick and made primarily of basalt, continental crust varies between 20 to 70 kilometers in thickness and is primarily composed of a volcanic class of silicates called granite.
Notably, the crust is the easiest layer for geologists to study and makes up only about 0.3% of the total mass of Earth. The continental crust covers about 45% of the surface, some of which lies beneath the oceans. The typical density of the crust, both oceanic and continental, is around 3 g/cm³.
The continental crust tends to be older and more complex than the oceanic crust. It consists of many different types of rocks formed over billions of years from many different types of processes. Due to the increased thickness and complexity of its composition, the continental crust is more buoyant than the oceanic crust and hence is not subducted during the process of plate tectonics. Oceanic crust, being thinner and denser often gets subducted beneath the continental crust at convergent boundaries.

what is transferred by a radio wave
A radio wave transfers energy and information through space via oscillating electric and magnetic fields.
A radio wave is a type of electromagnetic radiation that transfers energy through space. When a radio transmitter generates a signal, it creates a rapidly oscillating electric field, which in turn creates a magnetic field that propagates through the surrounding space at the speed of light.
This changing magnetic field induces a corresponding electric field in any conductive material (such as an antenna) that intercepts the wave. The electrical energy carried by the radio wave is then transformed into an electrical current that can be amplified and processed by electronic circuits.
In practical terms, radio waves are used to transmit various types of information, including voice and music for broadcasting, data for wireless communication, and navigation signals for GPS. The specific type of information transmitted by a radio wave is encoded in its frequency, amplitude, and modulation, which determine the characteristics of the wave and allow it to be decoded by the receiver.
Therefore, Through the use of oscillating electric and magnetic forces, radio waves transmit information and energy through space.

if you wanted to slow evaporation from a pot of coffee which of the following achieve this goal
Covering the coffee pot, lowering temperature, minimising surface area, utilising a thermal coffee pot, humidity control and limiting exposure prevent coffee evaporation and maintain flavour and warmth.
There are numerous ways to reduce coffee evaporation:
Evaporation can be reduced by covering the coffee pot. Water vapour molecules cannot escape via the lid. This prolongs the coffee's flavour and heat.
Lowering Temperature: Evaporation rates rise with temperature. Reduce coffee temperature to slow evaporation. For instance, you can put the coffee in an insulated container or let it cool down before serving. Be careful not to let it cool too much, as it may impair the taste.
Reduce Surface Area: Move the coffee to a container with less air exposure if possible. For instance, switching coffee from a pot with a large aperture to a thermal coffee pot with a narrower neck will reduce evaporation.
Use a Thermal Carafe: Thermal carafes keep hot beverages warm without direct heat. Heat loss and evaporation are reduced by their insulation.
Humidity Control: Evaporation rates depend on humidity. Dry air evaporates faster. By slowing evaporation, a humidifier may adjust indoor humidity.
Limit Exposure: Keep the coffee pot out of the air as much as possible. Return the pot to its covered position after pouring only what you need into your cup.
These strategies can reduce evaporation from a pot of coffee, maintaining its flavour and warmth for a better drinking experience.

Ben walks 500 meters from his house to the corner store. He then walks back toward his house, but continues 200 meters past his house to talk to a neighbor. It takes Ben 17 minutes from the time he leaves his house until he stops to talk to his neighbor. What is Ben’s average velocity?
Answer:
0.196 m/s
Explanation:
Average displacement is defined as the total displacement covered to the total time taken.
Total displacement = 500 - 500 - 200 = - 200 m
Total time taken = 17 minutes = 17 x 60 = 1020 second
So, Average velocity = 200 / 1020 = 0.196 m/s (magnitude only)
Answer:
Talking Ben is lazy so he would have gotten to the corner store on a scooter because hes to fat of a dog and he probley felt lazy and tired after going the the store and he probley sat back on his big fat red chair and burped his head off.

Assuming no air resistance, all projectiles have:
Explanation:
The motion of an object that move only under the action of gravity is called projectile motion.
All projectile have only acceleration due to gravity. In projectile motion, the horizontal movement of an object equals zero.
Equation of motion for a projectile are :
In horizontal motion,
Acceleration = [tex]a_x=0[/tex]
Velocity- time = [tex]v_x=v_{0x}[/tex]
Displacement - time, [tex]x=x_0+v_{0x}t[/tex]
In vertical motion,
Acceleration = [tex]a_y=-g[/tex]
Velocity- time = [tex]v_y=v_{0y}-gt[/tex]
Displacement - time, [tex]y=y_0+v_{0y}t-\dfrac{1}{2}gt^2[/tex]
Hence, this is the required solution.
When there is no air resistance, all projectiles accelerate in a vertical downward direction, which is equal to the acceleration due to gravity.
When an item is launched into the air, its motion is called a projectile motion when there is negligible air resistance and just gravity acting on it after the initial force that propels it into the air. A projectile is what it is, and its trajectory is what it took to get there.
The most important concept in projectile motion is that horizontal and vertical movements are independent of one another when air resistance is disregarded.

Which does not describe a physical change happening to water?
A physical change in water does not include breaking chemical bonds to form new substances. Therefore, the correct answer is the option that describes a chemical change, such as water reacting with another substance to form a different compound. For instance, water does not undergo a physical change when it reacts with sulfur dioxide to form sulfuric acid; this is a chemical change.
Physical changes are changes in the state or phase of a substance that do not involve altering the chemical composition. Examples of physical changes in water include melting (solid to liquid), freezing (liquid to solid), evaporation (liquid to gas), condensation (change from gas to liquid), and sublimation (solid to gas without becoming liquid). A charged atom is known as an ion. The term used to describe the mineral content of water is hardness. The gas that forms sulfuric acid when it reacts with water is sulfur dioxide. These concepts are fundamental in understanding the physical and chemical properties of substances, especially water, which is vital in chemistry and environmental science.
