Conduction, Convection, & Radiation24

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 infrared radiation, which can occur in a vacuum.

How does heat transfer from a hot object to a cold object?

Back

Heat transfers from a hot object to a cold object through conduction, convection, or radiation until thermal equilibrium is reached.

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 warm air rising and cool air sinking, creating a circulation pattern in a room.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin, even when standing in the shade.

Front

What happens to the temperature of a car's interior on a sunny day?

Back

The car's interior temperature rises due to radiation from the sun heating the surfaces inside the car.

Front

How does a heat pack warm cold feet?

Back

A heat pack warms cold feet through conduction, as the warmth from the pack is transferred to the feet.

Front

What is the role of insulation in heat transfer?

Back

Insulation reduces heat transfer by conduction, convection, and radiation, helping to maintain temperature.
