Internal energy in the particle model

Internal energy in the particle model

Particle model comparison of solid, liquid and gas showing particle motion, internal energy as total kinetic plus potential energy, and the note that temperature depends on average kinetic energy

A system is the object or group of objects you are focusing on, such as a metal block, a beaker of water, or a lump of ice. Its internal energy is the total kinetic energy and total potential energy of all its particles.
