Heat Transfer

Front

What is heat transfer?

Back

The movement of thermal energy from one object or substance to another.

Front

What are the three main types of heat transfer?

Back

Conduction, Convection, and Radiation.

Front

Define conduction.

Back

The transfer of heat through direct contact between materials.

Front

Give an example of conduction.

Back

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

Front

Define convection.

Back

The transfer of heat through the movement of fluids (liquids or gases).

Front

Give an example of convection.

Back

Warm air rising and cool air sinking in a room.

Front

Define radiation.

Back

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

Front

Give an example of radiation.

Back

The warmth felt from the sun on your skin.

Front

What happens to air when it is heated?

Back

It becomes less dense and rises.

Front

What is the role of density in convection?

Back

Less dense (warmer) fluids rise, while more dense (cooler) fluids sink.
