Conduction, Convection, and Radiation

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, which can occur in a vacuum.

Front

Example of conduction in everyday life?

Back

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

Front

Example of convection in everyday life?

Back

An example of convection is when warm air rises and cool air sinks, creating a breeze.

Front

Example of radiation in everyday life?

Back

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

Front

How does a hot spoon help scoop ice cream?

Back

The warmth of the spoon is conducted to the ice cream, making it easier to scoop out.

Front

What happens to water when it boils?

Back

When water boils, convection currents form as hot water rises and cooler water sinks.

Front

What type of heat transfer occurs when sitting by a campfire?

Back

The heat transfer that occurs is radiation.

Front

What is the role of insulation in heat transfer?

Back

Insulation reduces heat transfer by conduction, convection, and radiation.
