Conduction, Convection, & Radiation

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, which can occur through a vacuum.

Front

How does heat transfer occur between two objects?

Back

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

Front

What is an example of conduction?

Back

An example of conduction is when a metal spoon gets hot after being placed in a hot pot of soup.

Front

What is an example of convection?

Back

An example of convection is the warm air rising and cool air sinking in a room heated by a radiator.

Front

What is an example of radiation?

Back

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

Front

What happens to the temperature of a car's interior on a sunny day?

Back

The car’s inside temperature rises to over 100 degrees due to radiation from the sun.

Front

What is the primary mechanism of heat transfer in liquids?

Back

Convection is the primary mechanism of heat transfer in liquids.

Front

Can heat transfer occur in a vacuum?

Back

Yes, heat transfer can occur in a vacuum through radiation.
