Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through a solid material without the movement of the material itself. It occurs when two objects at different temperatures are in direct contact.

What is convection?

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases). It occurs when warmer areas of a liquid or gas rise and cooler areas sink, creating a current.

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium, so it can occur in a vacuum, such as the heat from the sun reaching the Earth.

How many kinds of heat transfer are there?

Back

There are three kinds of heat transfer: conduction, convection, and radiation.

Front

In which direction does heat transfer?

Back

Heat transfers from hot to cold.

What happens to cold air?

Back

Cold air is denser than warm air, so it falls.

What is an example of conduction?

Back

An example of conduction is when a metal spoon gets hot from being in a pot of boiling water.

What is an example of convection?

Back

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

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.

Front

What is the role of temperature in heat transfer?

Back

Temperature differences drive heat transfer; heat moves from areas of higher temperature to areas of lower temperature.
