Phase Changes - Heat Energy, Kinetic Energy, Thermal Energy, and Temperature

Connections between types of energy and an overview on phase changes

Phase Changes

Transition of matter from one state to another due to changes in temperature and pressure

Melting

Solid to liquid phase change

Freezing

Liquid to solid phase change

Vaporization

Liquid to gas phase change

Condensation

Gas to liquid phase change

Sublimation

Solid to gas phase change

Deposition

Gas to solid phase change

Kinetic Energy

Energy possessed by particles due to their motion

Thermal Energy

Total energy of all particles in a substance

Heat Energy

Energy transfer between objects due to temperature difference

Temperature

Measure of average kinetic energy of particles in a substance

Boiling water

Liquid water gains thermal energy, particles gain kinetic energy, and water changes to gas (vaporization)

Melting ice

Solid ice gains thermal energy, particles gain kinetic energy, and ice changes to liquid (melting)
