Define radiation.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, without the need for a medium.

What happens to warm air in a room?

Back

Warm air is less dense than cold air, so it rises, creating convection currents.

How does a lava lamp work?

Back

A lava lamp works through convection; the colored liquid forms globs that rise and fall as they are heated and cooled.

What is an example of convection?

Back

An example of convection is the warm air rising from a heater and circulating around a room.
