Thermal Energy

3. Particles in an object
7. Transfer of energy by electromagnetic waves
8. The transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from place to place
10. The sum of the kinetic and potential energy of all the particles in an object
11. It is impossible for heat to flow from a cool object to a warmer object unless work is done
13. The transfer of thermal energy
14. Thermal energy that flows from something at a higher temperature to something with lower temperature

1. The increase in thermal energy of a system equals the work done on the system plus the heat transferred to the system
2. Fuel is burned inside the engine chambers or cylinders
4. Thermal energy, heat, and work are related, and the study of the relationship among them
5. The Amount of heat that is needed to raise the temperature of 1kg of some material by 1°C
6. Absorbs radiant energy from the sun
9. Device that converts heat into work
12. Material in which heat flows slowly
