Conduction, Convection, and Radiation

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer parts of a fluid rise and cooler parts sink.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium, so it can occur in a vacuum.

Front

How does heat transfer occur when an egg is placed on hot pavement?

Back

The pavement conducts heat to the egg, cooking it.

Front

What happens when a heat pack is placed on cold feet?

Back

The warmth of the heat pack is conducted onto the cold feet, warming them up.

Front

What is an example of convection in everyday life?

Back

An example of convection is the movement of liquid in a lava lamp, where heated liquid rises and cooler liquid sinks.

Front

What is an example of radiation?

Back

An example of radiation is feeling warmth from a campfire without touching it.

Front

What is the main difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.

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 role of convection in weather patterns?

Back

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