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, like when you touch a hot pot.

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, creating a circulation pattern.

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, which is why you can feel warmth from a campfire without touching it.

What happens to warm air near a heater?

Back

Warm air near a heater rises toward the ceiling, moves toward the walls, and eventually sinks back down to the floor.

What happens when a car engine gets hot?

Back

When a car engine gets hot, conduction occurs as heat transfers from the engine parts to the surrounding air.
