Front

What is the law of conservation of energy?

Back

Energy can be transformed from one form to another, but the total amount remains constant.

Front

Define conduction in terms of energy transfer.

Back

Conduction is the transfer of heat through direct contact between materials.

Front

Define convection in terms of energy transfer.

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

Define radiation in terms of energy transfer.

Back

Radiation is the transfer of energy through electromagnetic waves.
