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, such as sunlight, which can travel through a vacuum.

Front

How does heat transfer from a hot object to a cold object?

Back

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

Front

What is an example of conduction?

Back

An ice cube melting in a person's hand is an example of conduction.

Front

What is an example of convection?

Back

When you are making soup and the water is rising and lowering is an example of convection.

Front

What is an example of radiation?

Back

The warmth felt from sunlight on your skin is an example of radiation.

Front

What happens to the temperature of a substance when it absorbs heat?

Back

The temperature of the substance increases when it absorbs heat.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What is the role of a conductor?

Back

A conductor is a material that allows heat to pass through it easily, such as metals.
