The blanks are filled for conduction convection and radiation out using the concept of heat energy and heat transfer.
What is heat transfer?
The heat transfer is the transfer of thermal energy due to the temperature difference. The heat flows from the higher temperature to the lower temperature.
The heat transfer of a closed system is the addition of change in internal energy and the total amount of work done by it.
Lets feel all the blanks as,
- 1) Heat is thermal energy which can do work.
- 2. Heat moves around the universe in conduction, convection, or radiation ways.
- 3. Hot air moving up is an example of convection.
- 4. A microwave oven uses radiation.
- 5. A metal spoon heated by hot soup is an example of conduction.
- 6. Molecules in cold things move more slowly than in hot things.
- 7. The ice sculpture more energy than. a lighted match, because it has more molecule.
- 8. The transfer of heat by currents through liquids or gases is called Convection.
- 9. An infrared camera in sensitive to -210 to -196 radiation.
- 10. Liquid Nitrogen’s temperature is minus -195.79 degrees Celsius.
- 11. A thermos bottle uses a vaccume flask to keep heat in the thermos.
- 12. A fire radiates infrared waves.
- 13. The paper spiral turns because of convection.
- 14. Heat is measured in Joule (SI) or British thermal unit (BTU) scale.
- 15. Cloth
Hence, the blanks are filled for conduction convection and radiation out using the concept of heat energy and heat transfer.
