Thermal Vocab puzzle

4. A measure of how well a system converts heat into useful work or energy.
7. The branch of physics that deals with the relationships between heat and other forms of energy.
8. A device that automatically regulates temperature.
9. A transition between different states of matter (solid, liquid, gas) due to heat transfer.
11. A material's ability to conduct heat.
12. The heat required to change the state of a substance (e.g., from solid to liquid) without changing its temperature.
14. Material or methods used to reduce the rate of heat transfer.
15. Heat energy stored within the Earth, often used for heating or electricity generation.
16. The amount of heat energy that must be removed from a space to maintain a desired temperature.
17. A device that transfers heat energy from a source to a destination.
19. The amount of heat energy required to raise the temperature of a substance.
20. The transfer of heat energy through electromagnetic waves.

1. A device that transfers heat from one medium to another without mixing the two.
2. The tendency of matter to change in volume in response to a change in temperature.
3. The amount of heat per unit mass required to raise the temperature of a substance by 1°C.
5. A substance used in a cooling system to absorb heat and produce cooling.
6. A measure of heat energy. One BTU is the amount of energy needed to raise the temperature of one pound of water by 1°F.
10. The transfer of heat through a material by direct contact of particles.
13. The transfer of heat by the movement of a fluid (liquid or gas).
18. A method of heating where heat is transmitted directly from a hot surface to an object without heating the intervening air.
