Front

What is thermal energy transfer?

Back

The process of heat moving 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

Define convection.

Back

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

Front

Define radiation.

Back

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

Front

How does heat transfer occur in a campfire?

Back

Heat is transferred to you by radiation from the flames.

Front

What happens to warm air in convection?

Back

Warm air rises because it is less dense than cool air.

Front

What type of heat transfer occurs in a hot air balloon?

Back

Convection, as the hot air inside the balloon rises.

Front

Give an example of conduction in everyday life.

Back

Ironing a shirt, where heat is transferred from the iron to the fabric.

Front

Give an example of convection in everyday life.

Back

Boiling water in a pot, where hot water rises and cool water sinks.
