Sublimation is an endothermic physical change (heat is needed).
I believe "heat"To change from one state of matter to another state of matter heat is added or taken away.I think that makes sense!
Of course heat is added because you are turning solid which is like ice to gas which is water vapour !!
Water changes to a solid, ice, when heat is taken away from it. You can think of putting water into the freezer. Since the freezer is cold, heat flows out of the water making it become ice cubes.
Sublimation is an endothermic phase transition from solid to gaseous state.
The complete subject of the sentence is "To change a liquid to a solid."
more or less heat

Heat is taken away during evaporation. As the liquid absorbs heat from its surroundings and gains energy, some of the molecules at the surface of the liquid gain enough energy to overcome the intermolecular forces holding them together, and they escape into the gas phase. This process removes heat from the remaining liquid, causing it to cool down.

It becomes cold.
It slows.
