Front

What are the three main types of heat transfer?

Back

Conduction, Convection, and Radiation.

Front

Define conduction.

Back

The transfer of thermal energy through direct contact between materials.

Front

Give an example of conduction.

Back

Burning your hand on a hot car door.

Front

Define convection.

Back

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

Front

Give an example of convection.

Back

Boiling water where hot water rises and cool water sinks.

Front

Define radiation.

Back

The transfer of thermal energy through electromagnetic waves without the need for a medium.

Front

Give an example of radiation.

Back

The sun melting snow on a cold winter day.

Front

What happens to gas particles when they are heated?

Back

They move faster and expand, taking up more space.

Front

What is thermal expansion?

Back

The increase in volume of a substance due to an increase in temperature.
