Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself. It occurs when two objects at different temperatures are in direct contact.

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, 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, meaning it can occur in a vacuum.

Front

How does heat flow between objects?

Back

Heat flows from a warmer object to a cooler object until thermal equilibrium is reached, meaning both objects are at the same temperature.

Front

What is an example of conduction?

Back

An example of conduction is when a metal spoon gets hot after being placed 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 happens to the temperature of water left out overnight?

Back

The temperature of the water will eventually equal the temperature of the air in the room due to heat transfer.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What role does insulation play in heat transfer?

Back

Insulation reduces the rate of heat transfer between objects, helping to keep heat in or out of a space.
