  1. 1. The conversion of liquid to gas.
  2. 2. 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.
  3. 3. The law that allows you to do calculations when the gas is constant (P1V1/T1 = P2V2/T2).
  4. 6. The conversion of liquid to gas, also known as the cooling process.
  5. 7. An increase in this will cause the molecules in a substance to move more rapidly.
  6. 9. Flows and can take the shape of it's container but has intermolecular attractions to keep the particles close together.
  7. 10. The conversion of a gas to a solid.
  8. 13. The conversion of gas to solid.
  9. 15. Consists of tiny particles that constantly moves rapidly and randomly.
  10. 16. The SI unit to measure temperature and it must be used for all gas laws (C + 273 = K)
