Heat Transfer

Front

What is heat transfer?

Back

The process of thermal energy moving from one object or substance to another due to a temperature difference.

Front

Name the three types of heat transfer.

Back

Conduction, Convection, and Radiation.

Front

What is conduction?

Back

The transfer of heat between materials in direct contact (touching).

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

The transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

How does heat transfer occur in Earth's mantle?

Back

Heat from the core drives convection currents in the mantle.

Front

What happens to the temperature of rock material as you move away from the Earth's core?

Back

The temperature of the rock material decreases.

Front

What is an example of conduction?

Back

A metal spoon getting hot when placed in a pot of boiling water.

Front

What is an example of convection?

Back

Warm air rising and cool air sinking in a room, creating a circulation pattern.

Front

What is an example of radiation?

Back

Feeling warmth from the sun on your skin.
