Question

why is heat energy needed to melt a solid ? what is the heat energy called​

Answer 1

Answer:

energy transfer

latent heat, also called the heat of vaporization, is the amount of energy necessary to change a liquid to a vapour at constant temperature and pressure. The energy required to melt a solid to a liquid is called the heat of fusion, and the heat of sublimation is the energy…

Hope it helps youhh

Answer 2

Answer:

Heat energy is required to melt a solid because the cohesive bonds between the molecules can move around at comparable kinetic energy;thus, there is no rise in temperature.

Heat energy is also called as thermal energy.

According to me these will be the answer
