Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one through physical touch.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm air or liquid rises while cooler air or liquid sinks, creating a circulation pattern.

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, allowing heat from the Sun to reach the Earth.

Front

What is an example of conduction?

Back

An example of conduction is when you touch a hot stove and feel the heat transfer to your hand.

Front

What is an example of convection?

Back

An example of convection is warm air rising in a room, causing cooler air to sink and create a circulation of air.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the Sun on your skin, even when you are not in direct contact with it.

Front

What is insulation?

Back

Insulation is a material that reduces the transfer of heat. It is used to keep heat in or out of a space.

Front

How does heat transfer from the Sun to the Earth?

Back

Heat from the Sun reaches the Earth through radiation.

Front

What happens to air when it is heated?

Back

When air is heated, it becomes less dense and rises, while cooler air sinks, creating convection currents.

Front

What is the role of a heat lamp?

Back

A heat lamp transfers heat to objects or living beings through radiation.
