Energy: Forms, Transformation, Transfer, and Conservation
Conduction is the transfer of energy that occurs when a warmer object (or quantities of a solid, liquid or gas) …
Item NG058003: Energy is transferred when a person comes in contact with cold air, and energy is transferred when an electric generator is used to run a motor.
Consider the following situations:
Situation 1: A person comes in contact with cold air.
Situation 2: An electric generator is used to run a motor.
Is energy being transferred in either of these situations?
- Energy is transferred in both situations.
- Energy is NOT transferred in either situation.
- Energy is transferred in Situation 1, but energy is NOT transferred in Situation 2.
- Energy is transferred in Situation 2, but energy is NOT transferred in Situation 1.

- PS3.B Energy can also be transferred from place to place by electric currents, which can then be used locally to produce motion, sound, heat, or light. The currents may have been produced to begin with by transforming the energy of motion into electrical energy.
PS3.B Energy is spontaneously transferred out of hotter regions or objects and into colder ones.
