Conduction, Convection, & Radiation

Front

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 through physical touch.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It creates currents as warmer, less dense areas rise and cooler, denser 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, allowing heat from the Sun to reach the Earth.

Front

Give an example of conduction.

Back

An example of conduction is when a metal spoon gets hot after being placed in a hot bowl of soup.

Front

Give an example of convection.

Back

An example of convection is the way warm air rises and cool air sinks, creating a current in a room heated by a radiator.

Front

Give an example of radiation.

Back

An example of radiation is feeling warmth from the Sun on your skin or from a heat lamp.

Front

What is the role of conduction in cooking?

Back

Conduction plays a role in cooking when heat is transferred from a hot pan to the food in contact with it.

Front

How does convection affect weather patterns?

Back

Convection affects weather patterns by creating wind and storms as warm air rises and cool air moves in to replace it.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.

Front

What is an example of radiation in everyday life?

Back

An example of radiation in everyday life is using a microwave oven, which heats food by emitting microwave radiation.
