Heat of fusion.
The energy required to melt a substance. (Apex)
The same amount of energy that is required to change it from a solid to a liquid. About 334.0 kJ/kg.
the energy that goes into changing a substance from a solid to a liquid (melting) is called the latent heat of fusion.
No. Solid, liquid, and gas are states of matter, not energy. - - -- --- Matter (things) have energy (not things), and things can be solid, liquid, gas, or the fourth state of matter, called plasma. Most of the sun is plasma, but about 9% of it is gaseous.
No. Latent heat of vaporization is defined as the energy required to VAPORIZE 1 kilogram of a liquid completely at its boiling point. Latent heat of sublimation is the energy required to SUBLIME 1 kilogram of a solid completely into a gas at constant temperature. They're different. Note that the temperatures should be constant during the processes.

No. Going from solid to liquid at constant temperature is an endothermic process. The required amount of energy is called "heat of fusion" of the material that changes state.
The amount of heat energy required to solid substance solid into a liquid state without any changes in temperature ______________________ Apex: The amount of energy required to turn a mole of a solid into a liquid
A material in solid phase changes to its liquid phase by absorbing energy. The intermolecular(inter-particular) bonds are broken as the temperature increases until enough bonds are broken that the rigid shape of the solid can no longer be maintained.*The energy required to turn a solid into a liquid, of the same temperature, is called the latent heat of fusion.
Energy is given off when cooling from a liquid to a solid. How much depends on the elements involved and the amount.
The energy required to go from a solid to a liquid-Apex
The heat energy required to change a substance between solid & liquid at constant temperature is called the "latent heat of fusion". If the change is from solid to liquid the substance gains this energy. If the change is from liquid to solid the substance gives up this energy. The exact amount of latent heat of fusion is different for different substances.
