Energy, Flows, and Feedbacks

2. System/Exchanges of matter or energy occur across system boundaries.
5. ability to do work or transfer heat.
6. Law of Thermodynamics/Energy can neither be created nor destroyed but can change from one form to another.
7. Radiation/A form of energy emitted by the Sun that includes, but is not limited to, visible light, ultraviolet light, and infrared energy.
9. State/A state in which inputs equal outputs, so that the system is not changing over time.
11. measure of the average kinetic energy of a substance.
13. addition to a system.
15. massless packet of energy that carries electromagnetic radiation at the speed of light.
16. amount of energy used when a 1-watt electrical device is turned on for 1 second.
17. Analysis/An analysis to determine inputs, outputs, and changes in a system under various conditions.
19. System/Matter and energy exchanges do not occur across boundaries.

1. Energy/Potential energy stored in chemical bonds.
3. Quality/The ease with which an energy source can be used for work.
4. loss from a system.
5. in a system.
8. rate at which work is done.
10. Feedback Loop/A system responds to a change by returning to its original state, or by decreasing the rate at which the change is occurring.
12. Energy/The energy of motion.
14. Feedback Loop/Change in a system is amplified.
15. Energy/Stored energy that has not been released.
18. Law of Thermodynamics/When energy is transformed, the quantity of energy remains the same, but its ability to do work diminishes.
