- 4. Average kinetic energy of molecules in a substance
- 5. The transfer of energy by direct contact from one molecule to another.
- 7. A liquid turns to a solid, energy is removed

- 11. The energy of motion
- 12. A liquid turns to a gas fast, energy is added
- 14. When energy is added, a solid turns to a gas, skipping the liquid phase
- 15. When a solid turns to a liquid and energy is added
Down
- 1. The movement of heat, mostly in a liquid or gas.
- 3. The total amount of kinetic energy in a substance
- 6. A phase change from gas to a liquid where energy is removed
