  1. 2. Has a definite shape and closely packed particles.
  2. 5. The law that allows the total pressure of a mixture of gases to equal to the sum of the pressures of all the gases in the mixture.
  3. 6. An empty space with no particles and no pressure.
  4. 7. When the three substances (solid, liquid, and gas) are in equilibrium.
  5. 9. The law that allows you to do calculations when the gas is constant (P1V1/T1 = P2V2/T2).
  6. 12. When a liquid is heated to a temperature at which particles throughout the liquid have enough kinetic energy to vaporize once the liquid begins to boil.

  1. 1. The term used to describe the movement of one material through another.
  2. 3. The escaping of gas through a small opening.
  3. 4. The conversion of liquid to gas.
  4. 8. Consists of tiny particles that constantly moves rapidly and randomly.
  5. 10. The conversion of gas to solid.
  6. 11. What law describes the nature of how the orderly state goes into the disorderly state.
  7. 13. Flows and can take the shape of it's container but has intermolecular attractions to keep the particles close together.
  8. 14. An increase in this will cause the molecules in a substance to move more rapidly.
