Energy and Thermodynamics Concepts

Front

Closed system

Back

A system in which matter cannot transfer in or out of the system, but energy can.

Front

Conduction

Back

The transfer of energy between objects or particles through direct contact.

Front

Convection

Back

The transfer of energy through currents in fluids.

Front

Gravitational potential energy

Back

Energy stored in an object due to its position in a gravitational field.

Front

Heat

Back

The transfer of thermal energy from a warmer object to a cooler object until equilibrium is reached.

Front

Kinetic energy

Back

Energy of objects in motion.

Front

Law of conservation of energy

Back

Energy can be transferred from object to object in a closed system, but it cannot be created nor destroyed.

Front

Radiation

Back

The transfer of energy by electromagnetic waves that travel through space without needing a medium.

Front

Temperature

Back

Measurement of the average kinetic energy of the particles in a substance or system.

Front

Thermal energy

Back

The energy within a system due to the movement of particles; measured as temperature.
