Convection, Conduction, Radiation

Front

What is Convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) where warmer, less dense areas rise and cooler, denser areas sink.

Front

What is Conduction?

Back

Conduction is the transfer of thermal energy through collisions between particles in a solid material.

Front

What is Radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light, without the need for a medium.

Front

Which method of heat transfer does not require a medium?

Back

Radiation does not require a medium for heat transfer.

Front

What happens to particles in a solid?

Back

In a solid, particles are closely packed together and vibrate in fixed positions.

Front

What happens to particles in a liquid?

Back

In a liquid, particles are close together but can move past one another, allowing liquids to flow.

Front

What happens to particles in a gas?

Back

In a gas, particles are far apart and move freely, resulting in low density.

Front

What is an example of conduction?

Back

An example of conduction is when a metal spoon gets hot from being in a pot of boiling water.

Front

What is an example of convection?

Back

An example of convection is the warm air rising from a heater and circulating in a room.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.
