Radiation, convection, conduction

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light, and does not require a medium to travel through.

Front

What is an insulator?

Back

An insulator is a material that reduces the flow of heat, preventing heat transfer.

Front

What is a conductor?

Back

A conductor is a material that allows heat to flow through it easily.

Front

How does heat transfer occur between hot and cold water?

Back

Heat (thermal) energy from the hot water is transferred to the cold water until they reach the same temperature.

Front

What type of heat transfer occurs when a pan touches a burner?

Back

Conduction occurs when the pan touches the burner, transferring heat directly.

Front

What is an example of convection in everyday life?

Back

An example of convection is the way warm air rises and cool air sinks in a room, creating a circulation of air.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin, even though you are not in direct contact with it.

Front

What happens to heat energy when it is transferred?

Back

Heat energy moves from areas of higher temperature to areas of lower temperature.
