Concept Explanation

This simulation demonstrates the Second Law of Thermodynamics in an idealized isolated system.

Isolated System: No energy or matter can enter or leave the container.

Entropy: A measure of the disorder or randomness of a system. Lower entropy means more order, higher entropy means more disorder.

Second Law: The total entropy of an isolated system can only increase over time or remain constant in ideal reversible processes. It never spontaneously decreases.

Observation: When you start with a separated state (hot particles on one side, cold on the other), the random movement of particles will lead to mixing, increasing the entropy (disorder). It is highly improbable for a mixed state to spontaneously return to a perfectly separated state.
