Heat Transfer: Conduction, Convection, Radiation (waves)

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, which can travel through a vacuum.

Front

How does temperature affect molecular movement?

Back

The quicker a molecule moves, the warmer it is; the slower a molecule moves, the colder it is.

Front

What is an example of conduction in everyday life?

Back

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

Front

What is an example of convection in everyday life?

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 in everyday life?

Back

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

Front

What happens to ice in a warm environment?

Back

Ice melts due to heat transfer from the warmer environment to the colder ice, primarily through conduction.

Front

What is the role of insulation in heat transfer?

Back

Insulation reduces heat transfer by conduction, convection, and radiation, keeping heat in or out of a space.

Front

Why do light waves travel in a straight line?

Back

Light waves travel in a straight line if there is nothing to interfere with them.
