Conduction, Convection, and Radiation Flashcardizz

Front

What is conduction?

Back

Conduction is the transfer of heat through a solid 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 liquids and gases caused by the movement of the fluid itself. Warmer, less dense fluid rises while cooler, denser fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light. It does not require a medium to travel through.

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 when you boil water in a pot and see the water moving in circular patterns.

Front

What is an example of radiation?

Back

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

Front

What is insulation?

Back

Insulation is a material that reduces the transfer of heat. It is not a method of heat transfer but rather a way to prevent heat loss.

Front

How does convection work in the atmosphere?

Back

In the atmosphere, warm air rises and cool air sinks, creating wind patterns and weather changes.

What happens to a crayon left in the sun?

Back

The crayon melts due to solar radiation heating the surface it is on, which then conducts heat to the crayon.

Front

Why does hot air rise?

Back

Hot air rises because it is less dense than cooler air, causing it to float upwards.
