Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance, which is related to its temperature.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

What is an insulator?

Back

An insulator is a material that reduces the flow of heat, preventing heat transfer.

Front

What is a conductor?

Back

A conductor is a material that allows heat to flow easily through it.

Front

Give an example of conduction.

Back

An ice cube melting in a person's hand is an example of conduction.

Front

Give an example of convection.

Back

A furnace heating the air in a school is an example of convection.

Front

Give an example of radiation.

Back

A group of friends gathering around a fire to stay warm is an example of radiation.

Front

What happens to particles in a substance when it is heated?

Back

When a substance is heated, its particles gain kinetic energy and move faster.
