What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. For example, when you touch a hot stove, heat transfers from the stove to your hand.

What is convection?

Back

Convection is the transfer of heat through liquids and gases. It occurs when warmer areas of a liquid or gas rise and cooler areas sink, creating a circulation pattern.

What is the primary way heat travels through liquids and gases?

Back

Convection is the primary way heat travels through liquids and gases.

What happens to air when it is heated?

Back

When air is heated, it becomes less dense and rises, creating convection currents.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.
