- 2. Energy that is transferred between objects due to a temperature difference between those objects
- 9. States that if the mechanical energy of a system is constant, the increase in the thermal energy of the system equals the sum of the thermal energy transferred into the system and the work done on the system.
- 11. The study of the relationship between thermal energy, heat, and work.
- 12. The transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from one place to another.
- 13. The sum of the kinetic and potential energy of the particles that make up an object
- 14. A device that converts some thermal energy into mechanical energy.
- 15. A material through which thermal energy moves slowly.
Down
- 1. States that energy spontaneously spreads from regions of higher concentration to regions of lower concentration.
- 3. The measure of the average kinetic energy of all the particles that make up an object
- 4. The amount of energy lost by one part of a system is the same amount of thermal energy gained by another part of the system.
- 5. The transfer of energy by electromagnetic waves.
- 6. The amount of heat needed to raise the temperature of 1 kg of a material 1°C.
- 7. A heat engine that burns fuel inside the engine in chambers or cylinders.
- 8. The transfer of thermal energy by collisions between the particles that make up matter.
- 10. A device used in an active solar heating system that transforms radiant energy from the Sun into thermal energy.
