Thermal Energy & Heat

2. Transfer of thermal energy by particles moving through a fluid.
4. An element that is a good conductor of heat and electricity.
6. State of matter that has a fixed volume but not a fixed shape.
10. SI scale for measuring temperature in which the freezing point of water is 273 K and the boiling point of water is 373 K.
12. Material that is a poor conductor of thermal energy.
14. Flow of particles in a fluid that occurs because of differences in temperature and density.
15. Energy that is transferred from one object or substance to another because of a difference in temperature between them.
16. The ability to do work.
18. The measure of the average kinetic energy of the particles in matter; a physical property of matter.
19. Transfer of thermal energy between particles of matter that are touching.

1. The amount of heat necessary to raise one mass unit of that substance by one temperature unit.
3. Material that is a good conductor of thermal energy.
5. The total energy of a substance due to the movement or vibrations of particles.
7. Process in which a liquid changes to a solid.
8. The simplest form of matter that has a unique set of properties.
9. The transfer of thermal energy by waves that can travel through air or even through empty space.
11. Substance that can flow and take the shape of its container; either liquid or gas.
13. Energy that an object has due to its motion.
17. State of matter that has neither a fixed volume nor a fixed shape.
