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.
Temperature is a measure of how fast molecules move. Temperatures affect the motion of molecules because when heat is added to molecules, so is energy. The energy makes the molecules move faster, which in turn causes them to hit other molecules and object harder. When they hit other molecules, they bounce back really far which is why the molecules expand when heated.
