Thermal Energy Transfer Review

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

Convection is the transfer of heat through the movement of fluids (liquids or gases) where warm air rises and cool air sinks.

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

A conductor is a material that allows heat to pass through it easily, such as metals.

An insulator is a material that does not allow heat to pass through it easily, such as rubber or wood.

Transformation is NOT a type of heat transfer.

Warm air rises because it is less dense than cool air.

Cool air falls because it is denser than warm air.

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

An example of convection is the way warm air circulates in a room when a heater is on.
