Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when two objects at different temperatures touch each other.

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when a hot liquid or air expands, becomes less dense, rises, and cooler, denser liquid or air sinks.

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through, allowing heat to be transferred through empty space.

Example of conduction in everyday life?

Back

An example of conduction is when you touch a hot stove and feel the heat transfer to your hand.

Front

Example of convection in everyday life?

Back

An example of convection is boiling water, where hot water rises to the top and cooler water sinks to the bottom.
