Answer:
Melting
Sublimation
Vaporization
Explanation:
There are mainly 3 states of matter: solid, liquid and gas. There is change in one state to another when there is heat transfer. when the atoms gain energy, there state changes from solid to liquid to gas. When the atoms lose energy, the state changes from gas to liquid to solid.
In Melting process, atoms gain energy and their state of the matter changes from solid to liquid.
In sublimation process, atoms gain energy and their state of the matter changes from solid directly to gas.
In vaporization process, atoms gain energy and their state of the matter changes from liquid to gas.
In rest of the processes, atoms lose energy.
