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.

What is Convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks.

What is Radiation?

Back

Radiation is the transfer of energy through electromagnetic waves. It does not require a medium and can occur in a vacuum.

Example of Conduction in everyday life?

Back

Touching a hot stove and feeling the heat transfer to your hand.

Front

Example of Convection in everyday life?

Back

Boiling water where hot water rises to the top and cooler water sinks to the bottom.

Example of Radiation in everyday life?

Back

Feeling the warmth of the sun on your skin.

What is the role of Convection in weather patterns?

Back

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

Front

How does Conduction occur in metals?

Back

Metals conduct heat well because their atoms are closely packed, allowing energy to transfer quickly.

Front

What is a real-world application of Radiation?

Back

Solar panels convert sunlight (radiation) into electricity.

Front

What happens to air during Convection?

Back

Warm air expands, becomes less dense, and rises, while cooler air sinks, creating a convection current.
