Convection, Conduction, and Radiation

Front

What is convection?

Back

Convection is the movement of energy that occurs due to differences in temperature and density, typically in fluids (liquids and gases).

Front

What happens to warm air in convection?

Back

Warm air rises and cool air sinks, demonstrating the process of convection.

Front

Give an example of convection.

Back

An example of convection is warmer water at the surface of a swimming pool.

Front

What is conduction?

Back

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

Front

What happens when you touch a hot pot?

Back

When you touch a hot pot, heat is transferred to your hand through conduction.

Front

What is radiation?

Back

Radiation is the transfer of energy by waves or rays, such as heat from the sun.

Front

How is energy transferred in radiation?

Back

Energy is transferred in radiation by waves or rays, without the need for a medium.

Front

What is an example of conduction?

Back

An example of conduction is a spoon in a bowl of soup becoming warmer.

Front

What is the primary mechanism of heat transfer in liquids and gases?

Back

The primary mechanism of heat transfer in liquids and gases is convection.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.
