1 Adding heat energy increases the motion of molecules. 2  Removing heat energy, or cooling, decreases the motion of molecules. 3  If heat is added to a solid, the molecules can move fast enough to change from a solid to a liquid.
If you heat a liquid like water up even more (like if you put it in a pot on the stove), then the molecules will move around so fast that they canât even hold on to each other at all. When this happens, all of the molecules go flying apart and become a gas (like when you boil water to make steam).
