1. D: Interpretation of Entropy on the Microscopic Scale- The Connection between Randomness and entropy 1. D I Entropy Change in Mixing of Two ldeal gases Consider an insulated rigid container of gas separated into two halves by a heat conducting partition so the temperature of the gas in each part is the same. One side contains air, the other side another gas, say argon, both regarded as ideal gases. The mass of gas in each side is such
