Problem #8 (25 points): Two 1.00 L containers of gases are connected so that the contents can mix. One container initially has 1.00 mol He gas and the other container initially has 2.00 mol O2 gas. The temperature of the gases decreases from 10.0 \\\\deg C to 67.0 \\\\deg C.\ A) Calculate the entropy change in J/K for O2 gas associated with the change in volume during the reversible adiabatic expansion. Do the same for the He. Assume a constant temperature for this calculation.
