take some ice (a solid) and melt it into water (a liquid)
Heat is added to a solid to make a liquid... this is called melting. some additional liquid (water,ethanol,acid…) also change solid into a liquid.
For some foods there is a phase change from solid to liquid. Everything becomes liquid when it is digested, but some foods are already liquid when you eat them.
heat
A solid is transformed in a liquid by melting; some solids are transformed directly in a gas by sublimation.
The change from a liquid to a solid is called solidification or freezing. It occurs when the temperature of the substance decreases below its freezing point, causing the particles to slow down and arrange themselves in a fixed, ordered structure. This transition involves the release of heat energy.
Solid to Liquid = MeltingLiquid to Gas = EvaporationboilingGas to Liquid = CondensationLiquid to Solid = Freezing
Called freezing, or in the case of lava and some other things, solidifying.
A physical change is a change that can be reversed easily and no new substances are made. Examples are state changes ie. solid to liquid or liquid to gas.
As the molecules in a body move with increased speed, i.e. increasing kinetic energy, it is possible that the body will change from the solid phase to the liquid phase, or the liquid phase to the gas phase, and in some cases from the solid directly to the gas phase.

Some will and some won't.
