What are the three main types of heat transfer?

Back

Conduction, convection, and radiation.

Front

Define conduction.

Back

The transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Define radiation.

Back

The transfer of heat in the form of electromagnetic waves, such as infrared radiation, without the need for a medium.

Give an example of radiation.

Back

The heat felt from the Sun on your skin.

Front

What is the direction of heat flow?

Back

Heat flows from an area of high temperature to an area of low temperature.

Front

What happens to heat when a hot object is placed in contact with a cooler object?

Back

Heat will transfer from the hot object to the cooler object until thermal equilibrium is reached.
