Thermal Energy - Heat Transfer

Front

What is thermal energy?

Back

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

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another.

Front

What is a thermal conductor?

Back

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

Front

What is a thermal insulator?

Back

A thermal insulator is a material that does not allow heat to easily pass through it.

Front

What are the three methods of heat transfer?

Back

The three methods of heat transfer are conduction, convection, and radiation.

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) due to differences in temperature.

Front

What is radiation?

Back

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

Front

Give an example of conduction.

Back

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

Front

Give an example of convection.

Back

An example of convection is warm air rising and cold air sinking in a room.
