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.
Key Concepts. 1  Heating a liquid increases the speed of the molecules. 2  An increase in the speed of the molecules competes with the attraction between molecules and causes molecules to move a little further apart. 3  Cooling a liquid decreases the speed of the molecules.sing what you know about the attractions between water molecules and the way heating affects molecular motion, explain why the volume of water in the cylinder increases when it is heated. Students should realize that the molecules in hot water move slightly further apart, accounting for the increased volume.
