Heat and Heat Transfer
Across
- 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.
Down
- 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.
