WebJul 10, 2024 · Note that work done by a system (here the water) decreases its internal energy. In the case of ice melting under atmospheric pressure, the volume contraction means that the internal energy increases due to work done on the system by the surroundings. This increase in internal energy is on top of the gain due to a transfer of … WebMar 29, 2024 · Latent heat is the total energy released or absorbed during a phase transition of a substance. You find it by multiplying the specific latent heat of a substance by its mass. It's also known as the heat of transformation. Specific heat capacity is the energy released or absorbed with the change in temperature by exactly 1 kelvin per 1 kilogram …
WebAnswer (1 of 6): Because the heat of vaporization is higher than the heat of fusion. It takes more energy to break the attraction between liquid phase molecules into gas then it does between solid phase molecules into liquid.
