Three Types of Heat Transfer

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, allowing heat to flow from the hotter object to the cooler one. Example: A metal spoon getting hot when placed in a pot of boiling water.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer areas of a liquid or gas rise and cooler areas sink, creating a circulation pattern. Example: Boiling water where hot water rises to the top and cooler water moves down.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium (like air or water) to transfer heat. Example: The warmth felt from sunlight on your skin.
