How does heat transfer occur?

Back

Heat transfer occurs through conduction, convection, and radiation.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids and gases).

Front

What is radiation?

Back

The transfer of heat in the form of electromagnetic waves.

Front
