Topic 9: Thermal Energy and Heat Transfer Concepts

Front

A measure of the energy of individual particles. Measured in degrees Celsius, °C.

Back

Temperature

Front

A measure of the total amount of energy in an object. Measured in joules, J.

Back

Thermal energy

Front

Material that allows heat to move quickly through it.

Back

Thermal conductor

Front

Material that only allows heat to travel slowly through it.

Back

Thermal insulator

Front

Transfer of thermal energy through solids by the vibration of particles.

Back

Conduction

Front

Transfer of thermal energy through fluids (liquids and gases), when hot particles rise.

Back

Convection

Front

Transfer of thermal energy as a wave. It does not require particles so can occur through a vacuum.

Back

Radiation

Front

Related to how hot or cold it is, measured in degrees Celsius.

Back

Temperature of an object

Front

A substance that transfers energy easily from the hot part to the cold part.

Back

Conductor

Front

A substance that does not transfer energy easily from the hot part to the cold part.

Back

Insulator
