Thermal Energy (Vocab 4 & 5)

3. The total kinetic and potential energy of all the particles of an object.
6. An increase in the size of a substance when its temperature is increased.
9. Energy cannot be created or destroyed, it can only change forms.
10. The transfer of energy by electromagnetic waves.
13. A circular movement of a fluid (gas or liquid) caused by the cycle of warm fluid rising and cool fluid sinking.
16. A material that does not transfer thermal energy easily - it resists the gain or loss of temperature.
17. The energy that is transferred from a warmer object to a cooler object.
18. A measure of how hot (or cold) something is.
19. A state of matter that has a definite shape and volume.

1. An decrease in the size of a substance when its temperature is decreased.
2. Finding ways to use less energy or to use energy more efficiently.
4. Stored energy due to the position or shape of an object or its particles.
5. The energy due to the motion of an object or its particles.
7. For 1 gram of a substance, the amount of energy required to raise its temperature by 1 Kelvin.
8. A state of matter that has no definite shape or volume.
11. The transfer of thermal energy by the circulation or movement of a liquid or gas.
12. A state of matter that has a definite volume but no definite shape.
13. The transfer of thermal energy from one particle of matter to another.
14. A measure of the average kinetic energy of the particles in an object.
15. A material that transfers thermal energy easily.
