Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when faster-moving particles collide with slower-moving ones, transferring energy.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warmer, less dense fluid rises while cooler, denser fluid sinks, creating a circulation pattern.

Front

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, allowing heat to be transferred through empty space.

Front

What is an example of conduction?

Back

An example of conduction is when a metal spoon becomes hot after being left in a pot of hot soup.

Front

What is an example of convection?

Back

An example of convection is the way warm air rises and cool air sinks in a room, creating a circulation of air.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin, even when you are not in direct contact with it.

Front

What is insulation?

Back

Insulation is a material that reduces the transfer of heat. It is not a method of heat transfer but rather a way to prevent heat loss.

Front

How does heat move?

Back

Heat moves from warmer areas to cooler areas until thermal equilibrium is reached.

Front

What happens to particles in conduction?

Back

In conduction, particles in a hotter region vibrate faster and collide with neighboring cooler particles, transferring energy.

Front

What happens to fluids in convection?

Back

In convection, warmer fluids become less dense and rise, while cooler fluids become denser and sink, creating a cycle.
