Across
- 2. molecules flow and vibrate close together
- 4. Point the temperature at which a liquid turns into a gas
- 5. a substance that moves heat energy well
- 7. Point the temperature at which a liquid turns into a solid
- 13. energy stored energy
- 15. a substance that doesn't conduct (transfer) heat well
- 16. to get smaller, when a substance loses heat energy it contracts
- 17. the average kinetic energy of the molecules in a substance
Down
- 1. heat energy moving in currents
- 3. Energy energy from the flow of charged particles/current (electrons)
- 6. heat energy moving between two touching objects
- 8. to get bigger; adding heat to a substance makes it expand
- 9. energy energy of motion
- 10. energy from the sun moving in waves or rays
- 11. the molecules move fast and far apart
- 12. the building blocks of substances (combined atoms)
- 14. molecules vibrate in one position, they don't spin or flow
