Conduction, Convection, Radiation

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, and does not require a medium to travel.

Front

What happens to warm air in a room?

Back

Warm air rises because it is less dense than cooler air, leading to convection currents.

Front

How does a fire warm a group of friends?

Back

A fire warms friends through radiation, as heat is emitted in all directions from the flames.

Front

What is heat?

Back

Heat is the energy transferred from an object at a higher temperature to an object at a lower temperature.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in an object, related to its temperature.

Front

What is an example of conduction?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of convection?

Back

An example of convection is the circulation of warm air in a room heated by a radiator.

Front

What is an example of radiation?

Back

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