Heat and Heat Transfer

3. describes the TOTAL KINETIC ENERGY (energy of movement/vibration) possessed by the molecules that make up the object
5. ............... radiation = heat energy transferred by process of Radiation.
6. is the movement of heat in the form of electromagnetic waves, which can travel through space. There is no direct contact with the heat source.
7. The element of a kettle is located at the base and heat is ............ through the water by convection
11. .............. zero = -273°C = no kinetic energy in molecules = no heat energy.
12. is the transfer of heating a liquid or gas due to less dense, warmer particles rising and more dense, cooler particles falling.
14. Temperature and heat are considered to be ............... in science.
15. is a measure of the AVERAGE KINETIC ENERGY of the molecules in an object.
18. A substance that allow heat to flow through it.

1. Gases are ......... conductors of heat.
2. Objects with lower temperatures can in fact possess a greater amount of heat ...........
3. The .......... the object the more heat it radiates.
4. ........ temperature = each molecule has a lot of kinetic energy (moving lots, colliding lots, feels hot).
5. A material that does not conduct heat.
8. On a warm day a double story house is warmer up stairs because of convection ..............
9. .......... such as Copper and Gold are good conductors of heat.
10. Heat energy is transferred from objects with .............. heat energy to another object with less heat energy.
12. is a method of heat transfer in which heat is passed by vibration of particles to particles nearby. Involves direct contact with the heat source.
13. ............ energy is the energy of movement such as vibration.
16. P........., air, foam, rubber and wood are good insulators.
17. ........ temperature = each molecule has a small amount of kinetic energy (moving a less, colliding less, feels cold).
19. .......... coloured objects are good absorbers of radiation.
