Thermal Energy

5. A material, such as metal, that transfers heat energy easily.
6. A measure of the average kinetic energy of the particles in an object or substance.
10. The temperature scale commonly used in the US where water freezes at 32° and boils at 212°.
11. The scientific temperature scale based on absolute zero where atoms theoretically stop moving.
12. The transition of a substance from a liquid state to a gas state.

1. A material that does not allow heat energy to pass through it well, such as plastic or wood.
2. CURRENT The circulation of warm and cold fluid created during the convection process
3. The phase change where a solid turns directly into a gas without becoming a liquid.
4. Heat transfer in fluids (liquids or gases) caused by hotter, less dense fluids rising and cooler fluids sinking.
7. The transfer of heat through empty space by invisible electromagnetic ray
8. ENERGY The internal energy of a system or substance associated with its temperature and amount of matter
9. The flow or transfer of thermal energy from warmer places to cooler places.
