  1. 5. The energy an object has due to its motion.
  2. 6. The energy a substance must absorb in order to change from a solid to a liquid.
  3. 9. The phase change in which a substance changes from a gas or vapor to a liquid.
  4. 12. The result of a force distributed over an area.
  5. 13. The phase change in which a gas or vapor changes directly into a solid without first changing into a liquid.
  6. 16. The phase change in which a substance changes from a liquid into a gas.

  1. 1. The state of matter in which a material has definite volume but not a definite shape.
  2. 2. The inverse variation of the volume of a gas with its pressue if the temperature and the number of particles are constant.
  3. 3. A reversible physical change that occurs when a substance changes from one state of matter to another.
  4. 4. The energy a substance must absorb in order to change from a liquid to a gas.
  5. 7. The pressure caused by the collisions of particles in a vapor with the walls of a container.
  6. 8. A temperature of 0 kelvins.
  7. 10. The process that changes a substance from a liquid to a gas at temperature below the substance's boiling point.
  8. 11. A description of a change in which a system absorbs energy from its surroundings.
  9. 14. The direct proportion of the volume of a gas to its temperature (in kelvins) if the pressure and the number of particles of the gas are constant.
  10. 15. A description of a change in which a system releases energy to its surroundings.
