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 temperature differences.

Front

Define radiation.

Back

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

Front

What causes warm air to rise in a room?

Back

Convection, as warm air is less dense than cooler air.

Front

How does a lava lamp demonstrate convection?

Back

The colored liquid inside rises and falls due to temperature differences, creating movement.
