As molecules in a solid get hotter, they vibrate faster and faster and eventually slip out of their lattice-work pattern. When this occurs, the substance melts, changing from a solid to a liquid state

Heat refers to quantity of hotness, and is determined by the mass and speed of molecules. This program demonstrates that a bucket of water at a temperature of 50?C contains more heat than a cup of water at 100?C.
