Conduction, Convection, and Radiation Flashcardizz

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight reaching the Earth.

Front

How does heat move between objects?

Back

Heat always moves from areas of high temperature to areas of low temperature.

Front

What happens to the density of air when it is heated?

Back

Hot air becomes less dense than cold air, causing it to rise.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a pot of boiling water.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room, creating a circulation of air.

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 the role of insulation in heat transfer?

Back

Insulation reduces the transfer of heat, keeping warm air in during winter and cool air in during summer.

Front

What is the primary method of heat transfer from the Sun to the Earth?

Back

The primary method of heat transfer from the Sun to the Earth is radiation.
