Across
- 5. easily allow heat transfer(most metals)
- 8. the amount of energy that is required to a activate atoms or molecules
- 9. heat transfers through waves(flow of electromagnetic radiation)
- 11. energy is absorbed by the reaction from the surroundings
- 13. law establishes thermal equilibrium
- 14. moves between materials or changes form
- 15. energy of motion
- 16. energy conservation, asserts that energy cant be created or destroyed
- 17. Energy forms and changes
- 18. energy at rest
Down
- 1. introduces the concept of entropy
- 2. heat always moves from hot to cold
- 3. hot air currents going to the ceiling or roof
- 4. anything that had mass and takes up space
- 6. change measures the amount of heat released or absorbed
- 7. requires touch for transfer
- 10. states that as the temp approaches absolute zero entropy approaches 0
- 11. energy is released by the reaction of surroundings
- 12. the amount of heat needed to raise the temp of one gram to 1 degree c
