Across
- 3. most liquids and metals expand as their temperature rises and contracts as it decreases
- 5. energy can flow from a colder object to warmer object only if something does work
- 6. warm rises, cool sinks
- 10. the temperature scale in which the freezing point of water is 273 K and the boiling point is 373 K; 0 K is absolute zero
- 11. the study of thermal energy and heat and how they relate to work and other forms of energy
- 12. substances that can flow
- 13. the movement of thermal energy from a substance at a higher temperature to one at a lower temperature
Down
- 1. the principle of conservation of energy. Energy can be transferred and transformed, but it cannot be created or destroyed
- 2. the transfer of energy by electromagnetic waves; heat from the sun or a campfire
- 4. the temperature scale on which water freezes at 0 degrees and boils at 100 degrees
- 7. the direct transfer of heat from one substance to another substance that it is touching
- 8. absolute zero
- 9. force per unit area
