Energy & Energy Transfer

Front

What is radiation?

Back

Radiation is the transfer of energy through space without the need for a medium, such as warming up near a campfire.

What is an example of conduction in everyday life?

Back

An example of conduction is touching a hot metal spoon that has been in a pot of boiling water.
