Heat Transfer Practice

Front

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.

Front

What is convection?

Back

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

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

Example of conduction in everyday life?

Back

Walking on hot sand with bare feet is an example of conduction, as heat is transferred from the sand to your feet.

Front

Example of convection in everyday life?

Back

Boiling water is an example of convection, as the hot water rises to the top while cooler water sinks.

Front

Example of radiation in everyday life?

Back

The warmth felt from the sun on your skin is an example of radiation, as heat travels through space.

Front

What happens to particles during conduction?

Back

In conduction, particles vibrate and transfer energy to neighboring particles when they collide.

Front

What happens to particles during convection?

Back

In convection, warmer particles move up while cooler particles move down, creating a cycle of heat transfer.

Front

What happens to particles during radiation?

Back

In radiation, energy is emitted in the form of waves and does not require particles to transfer heat.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.
