  3. 6. Related to an object's elastic potential energy.
  4. 7. A device that bends in response to a temperature change is a ___________ strip.
  5. 10. Term that refers to liquids that evaporate rapidly.
  6. 11. The process by which heat flows through materials and between objects in direct contact.
  7. 12. Heat that causes matter to change state but produces no change in temperature.

  1. 1. An object's internal energy caused by random motions of its individual molecules.
  2. 2. The state in which there is no transfer of thermal energy between two objects.
  3. 3. The ratio of an object's heat capacity to the object's mass.
  4. 8. The device used to measure the heat of a process.
  5. 9. Holds together the nucleus of an atom.
  6. 13. Gaps that allow a bridge to change length as the temperature changes.
  7. 16. A theoretical device that would generate the maximum possible amount of work from a given amount of heat.
  8. 17. The form of energy that uses motion and forces to affect a whole object.
  9. 19. In thermodynamics, the portion of the universe NOT being studied.
