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 infrared radiation, and does not require a medium.

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 ice cube melting in a person's hand.

Front

What is an example of convection?

Back

When you are making soup and the water is rising and lowering.

Front

What is an example of radiation?

Back

The sun heating water in a swimming pool.

Front

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

Back

The temperature of the substance increases.

Front

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

Back

The temperature of the substance decreases.

Front

What is the role of a heat pack?

Back

A heat pack transfers heat to the body through conduction, warming the area it is applied to.
