Calculate the energy transferred when 4.6g of ice is melted at 0.0c

Answers

Answer 1

Final answer:

The energy transferred when 4.6g of ice is melted at 0.0C can be calculated using the formula Q = mLf, where Q is the heat needed to melt the ice, m is the mass of the ice, and Lf is the latent heat of fusion of water. Substituting the given values, we find that 1536.4 Jules of energy gets transferred.

Explanation:

To calculate the energy transferred when ice is melted, we use the formula Q = mLf, where Q is the heat necessary to melt the ice, m is the mass of the ice, and Lf is the latent heat of fusion of the substance (the energy needed to change the substance from solid to liquid state without changing its temperature). For water, Lf is 334 kJ/kg. So, to find the energy needed to melt 4.6g of ice we rearrange the formula and find: Q = (4.6/1000 kg) x 334,000 J/kg = 1536.4 J. Therefore, 1536.4 Jules of energy gets transferred when 4.6g of ice melts at 0.0C.
