What is Radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through.

Front

What is Convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm air rises while cool air sinks.

Front

What is Conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when two objects at different temperatures touch each other.

Front

What is a Comet?

Back

A comet is a body of ice and dust that orbits the Sun, often developing a tail when it comes close to the Sun.

Front

What is the Earth's atmosphere primarily composed of?

Back

The Earth's atmosphere is primarily composed of nitrogen and oxygen.

Front

How does heat transfer through Radiation?

Back

Heat transfer through radiation occurs when energy is emitted in the form of electromagnetic waves, such as sunlight warming your skin.

Front

What is an example of Convection in everyday life?

Back

An example of convection is boiling water, where hot water rises to the top and cooler water sinks.

Front

What is an example of Conduction?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is the difference between Convection and Conduction?

Back

Convection involves the movement of fluids to transfer heat, while conduction involves direct contact between materials.

Front

What is the role of the Sun in the formation of a comet's tail?

Back

The Sun's heat causes the ice in a comet to vaporize, creating a tail that points away from the Sun.
