Atoms and Molecules

Atoms and molecules are tiny particles of matter. A bunch of atoms make up a molecule. Atoms and molecules or "stuff" make up everything in the universe. Atoms and molecules are always constantly moving. The faster they move the more heat they generate, however, heat energy is also generated  by how many atoms and molecules are in the object. For example, a giant ice sculpture generates more heat than a match. Although, in the match, the molecules are moving faster, the ice sculpture has slower moving molecules, but A LOT more molecules than the match.
