Across
- 1. To transfer srom one place to another
- 2. the sum of energy of the molecules making up a substance; for this unit it is used to mean heat

- 15. a device that changes mechanical energy into electricity
- 17. The process of energy moving from one place or object to another
- 18. the flow of energy from one place to another
- 22. A change where energy is absorbed; this is usually felt as a loss of heat from the surroundings or the feeling of cold
