- 10. Term that refers to liquids that evaporate rapidly.
- 11. The process by which heat flows through materials and between objects in direct contact.
- 12. Heat that causes matter to change state but produces no change in temperature.

Down
- 1. An object's internal energy caused by random motions of its individual molecules.
- 2. The state in which there is no transfer of thermal energy between two objects.
- 3. The ratio of an object's heat capacity to the object's mass.
- 8. The device used to measure the heat of a process.
- 9. Holds together the nucleus of an atom.
- 13. Gaps that allow a bridge to change length as the temperature changes.
- 16. A theoretical device that would generate the maximum possible amount of work from a given amount of heat.
