Phase changes requiring the addition of heat energy are the phase changes from solid to liquid, liquid to gas, and solid to gas. These phase changes are termed melting (solid to liquid), evaporation (liquid to gas), and sublimation (solid to gas).
Based on chemical properties exothermic phase changes are those that release energy. The exothermic phase changes are gas--> liquid, liquid --> solid, and gas--> solid. Looking at a phase diagram if you are going up the "stairs" the conversions require energy going down the "stairs" energy is released.
Gas to liquid change releases energy.
The heat energy in the milk had to be removed in order to change the phase of milk.

It is converted to bond energy
Liquid to solid
Heat energy changes.
It doesn't change notwithstanding heat energy changes.
