Conduction, Convection, & Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a warmer object to a cooler one through physical touch.

Front

What is convection?

Back

Convection is the transfer of heat through liquids and gases caused by the movement of the fluid itself. Warm fluid rises while cooler fluid sinks, creating a circulation pattern.

Front

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 move through space.

Front

Example of conduction in everyday life?

Back

Touching a hot stove and feeling the heat transfer to your hand.

Front

Example of convection in everyday life?

Back

Boiling water in a pot where the hot water rises and the cooler water sinks.
