Heat Transfer

Front

What is heat transfer?

Back

Heat transfer is the process of thermal energy moving from one object or substance to another due to a temperature difference.

Front

What are the three types of heat transfer?

Back

The three types of heat transfer are conduction, convection, and radiation.

Front

Define conduction in heat transfer.

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

Give an example of conduction.

Back

An example of conduction is walking on warm sand, where heat transfers from the sand to your feet.

Front

Define convection in heat transfer.

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warmer areas of a fluid rise and cooler areas sink.

Front

Give an example of convection.

Back

An example of convection is warm air rising and cool air sinking, creating a circulation pattern.

Front

Define radiation in heat transfer.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, without the need for a medium.

Front

Give an example of radiation.

Back

An example of radiation is feeling the warmth of the sun on your skin.

Front

How does heat flow in heat transfer?

Back

In heat transfer, heat always flows from the hotter substance to the colder substance.

Front

What role does convection play in Earth's tectonic plates?

Back

Convection is responsible for the movement of Earth's tectonic plates, as hot magma rises and cooler magma sinks.
