Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat from one object to another through direct contact.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

What happens to air when it is heated?

Back

When air is heated, it expands, becomes less dense, and rises.

Front

What is an example of conduction?

Back

Walking on warm sand with bare feet is an example of conduction.

Front

What is an example of convection?

Back

Boiling water is an example of convection, as the hot water rises and cooler water sinks.

Front

What is an example of radiation?

Back

The warmth felt from sunlight is an example of radiation.

Front

Which method of heat transfer does not require a medium?

Back

Radiation does not require a medium for heat transfer.

Front

What is insulation?

Back

Insulation is a material that reduces the rate of heat transfer.

Front

What type of heat transfer occurs when you touch a hot stove?

Back

Conduction occurs when you touch a hot stove.
