Ch 12 Thermal Energy
Across
- 3. device that is able to continuously convert thermal energy to mechanical energy
- 6. rates of thermal energy transfer between two objects are equal
- 7. the sum of kinetic and potential energies of the particles that make up an object
- 10. whenever there is an opportunity of energy dispersal, the energy always spreads out
- 12. amount of energy that must be added to a unit mass of material to raise its temperature by one temp unit
- 13. transfer of energy by electromagnetic waves
- 14. the amount of thermal energy needed to melt 1 kg of a substance
- 15. the thermal energy needed to vaporize 1kg of a liquid
Down
- 1. heating caused by the motion of fluid in a liquid or gas due to temperature differences
- 2. the SI Unit of work and energy
- 4. transfer of thermal energy that occurs when particles collide
- 5. change in thermal energy of an obj is equal to the heat that is added to the obj minus the work done by the obj.
- 8. transfer of thermal energy
- 9. the measure of the dispersal of energy
- 11. measure of the average kinetic energy of the particles in an object
