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.
In an inverse way heat leaves a gas to change the molecular bonding when the gas condenses into a liquid, and heat leaves a liquid to change the molecular bonding when it freezes into a solid. In none of these changes of state is the heat (energy) that is input or output used to change the speed of the molecules.
