Entropy Change when Ideal Gases Mix (Interactive Simulation) In this Demonstration, ideal gases A and B are mixed isothermally by keeping the total volume constant ("remove barrier" option) or by adding gas A to gas B so the final volume is the same as the initial volume of B ("compress right" option).
entropy and indeed predicts So(0K) = 0. This leads to the following interesting corollary: It is impossible to decrease the temperature of any system to T = 0 K in a finite number of steps. How can we rationalize this statement? Recall the fundamental equation, dU = T dS – p dV dU = Cv dT For 1 mole of ideal gas, P = RT/V
