Across
- 5. Increase in volume of a substance when heated
- 8. Energy Total kinetic and potential energy of all particles in an object
- 9. Change Change from solid to liquid to gas (or reverse) without temperature change
- 10. Joint Gap left in bridges or sidewalks to allow for thermal expansion
- 11. Transfer of heat through direct contact of particles
- 12. Transfer of thermal energy from a hotter object to a colder object
- 14. State when two objects in contact reach the same temperature
- 15. Temperature scale where water freezes at 0° and boils at 100°
Down
- 1. Decrease in volume of a substance when cooled
- 2. Strip Two different metals bonded together; bends when temperature changes
- 3. Type of energy related to motion of particles
- 4. SI unit for heat and thermal energy
- 6. Measure of the average kinetic energy of particles in a substance
- 7. Temperature scale starting at absolute zero; no negative numbers
- 13. Zero Lowest possible temperature (0 K); particles have minimum energy
