- 6. An instrument used to measure changes in thermal energy
- 9. The transfer of thermal energy from one object to another because of temperature difference
- 10. Inclined plane wrapped around a cylinder
- 11. Consists of two disks or cylinders, each one with a different radius
- 12. Consists of a rope that fits into a groove in a wheel
- 15. Ratio of work output to work input
- 17. Rigid bar that is free to move around a fixed point
- 18. The transfer of energy by waves moving through space. As an object’s temperature increases, the rate at which it radiates energy increases.

- 24. Slanted surface along which a force moves an object to a different elevation
- 25. _________________reactions - take in heat
Down
- 1. Transfer of thermal energy with no overall transfer of matter

- 8. The study of conversions between thermal energy and other forms of energy
- 13. V-shaped objects whose sides are inclined planes sloped toward each other
- 14. Unit of measure for power
- 16. The transfer of thermal energy when particles of a fluid move from one place to another via convection currents.
- 20. ___________reactions - give off heat
- 21. Unit of measure for Work
