Convection, Conduction, and Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when two objects at different temperatures touch each other.

Front

Give an example of conduction.

Back

An example of conduction is an egg cooking in a frying pan.

Front

What is convection?

Back

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

Front

Give an example of convection.

Back

An example of convection is water boiling in a pot.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through.

Front

Give an example of radiation.

Back

An example of radiation is heat from the sun warming your skin.

Front

How does heat transfer between two objects at different temperatures?

Back

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

Front

What happens to thermal energy when two objects at different temperatures are in contact?

Back

Thermal energy passes from the warmer object to the cooler object.

Front

What is the main way heat is transferred when using a microwave?

Back

The main way heat is transferred in a microwave is through radiation.

Front

What is an example of conduction in everyday life?

Back

Touching a hot piece of metal is an example of conduction.
