Since the concepts covered in Chapter 1 apply to both atoms and molecules, the term particle is used as a generic term to include both. Adding heat energy to particles either raises the temperature and they move faster, or bonds are broken to change from solid to liquid (melting) or liquid to gas (boiling). Instead, allow the color to slowly mix into the water on its own. Why do you think the water keeps its shape the moment the balloon is popped? Continue the discussion by using water as an example.
