Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one.

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases). Warm fluid rises while cooler fluid sinks, creating a circulation pattern.

How does conduction occur in solids?

Back

In solids, conduction occurs as vibrating particles collide with neighboring particles, transferring energy.

How does convection occur in liquids?

Back

In liquids, convection occurs as warmer, less dense liquid rises and cooler, denser liquid sinks, creating a current.

What is an example of thermal radiation?

Back

The warmth felt from sunlight on your skin.

Front

What is the role of convection in weather patterns?

Back

Convection helps distribute heat in the atmosphere, leading to wind and weather changes.
