  7. 16. The conversion of a solid to gas.
  8. 18. Known as the cooling process.
  9. 19. Flows and can take the shape of it's container but has intermolecular attractions to keep the particles close together.

  1. 1. The conversion of liquid to gas.
  2. 3. In Boyle's gas law, the volume of the gas varies _________ with the pressure.
  3. 4. The law that allows you to do calculations when the gas is constant (P1V1/T1 = P2V2/T2).
