Gas Mixing & Entropy
This interactive simulator explores Gas Mixing & Entropy in Thermodynamics. Two species separated then mixed; ΔS = 2nR ln 2 for equal volumes and moles. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Thermodynamics.

How it works
Mixing of distinct ideal gases at constant T increases entropy because each species spreads into twice the volume. Identical particles require quantum Gibbs paradox treatment; here we show the classical distinguishable mixing case.
