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 in a vacuum, such as the heat from the Sun reaching the Earth.

Front

How does heat flow between the ice cap and water?

Back

Heat flows from the water to the ice cap, causing the ice to melt.

Front

What happens to the handle of a metal spoon in hot soup?

Back

The handle warms up due to conduction, as heat is transferred from the hot soup to the spoon.

Front

How does the Sun transfer heat to the Earth?

Back

The Sun transfers heat to the Earth through radiation.

Front

What is an example of convection in a house?

Back

Warm air rises and cool air sinks, creating a circulation of air that helps to distribute heat.

Front

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

Back

A car’s inside temperature can rise to over 100 degrees due to radiation from the Sun.

Front

What is an example of conduction in everyday life?

Back

Touching a hot stove and feeling the heat transfer to your hand is an example of conduction.

Front

What is an example of convection in cooking?

Back

Boiling water in a pot where the hot water rises and cool water sinks is an example of convection.
