Phase Changes. There are forces of attraction and repulsion that exist between molecules of all substances. These intermolecular forces allow molecules to pack together in the solid and liquid states. When a pot of water is placed on a burner, it will soon boil.
Give one word or term for each of the following descriptions. The change in phase from a solid to a gas. The change in phase from liquid to gas.
Heating Curves represent the energy of phase changes. To calculate the energy change during phase changes you will need to use Heats of fusion or vaporization.
