is when the solid is hard then the word is Melting to change to liquid
Changing from a solid to a liquid is a physical change as is changing from a liquid to a gas.
The physical change of a solid to a liquid at the melting point called melting.
The change in state would be known as freezing. Just for your information: Solid to Liquid = Melting Liquid to Gaseous = Boiling Solid to Gaseous = Sublimation Gaseous to Liquid = Condensation Liquid to Solid = Freezing Gaseous to Solid = Deposition

energy is required
heat of vaporization
The energy required to melt a substance. (Apex)
When a substance is below the triple point, the equilibrium will be between solid and vapor rather than solid/liquid or liquid/vapor. Sublimation is the direct change from solid to vapor without any intermediate phase change. The latent heat of sublimation is the energy required to change a given quantity of solid into the vapor at equilibrium. It is analogous to (but not the same as) latent heat of melting (energy required to melt the solid to liquid) and latent heat of vaporization (energy required to change a liquid into a gas).
is when the solid is hard then the word is Melting to change to liquid
It is the amount of energy required to change 1kg of solid into a liquid with no temperature change.
The same amount of energy that is required to change it from a solid to a liquid. About 334.0 kJ/kg.
change of a liquid to a solid
The change from liquid to solid is called freezing.
Sure, change from solid to liquid is a physical change
Only one . . . . . heat energy.
when ice was solid change liquid because sun was very hot. ice will change liquid change back solid again
