Mixing! n moles of Ar and In moles of Xe (treated as ideal gases) are in adjacent containers with volumes of V and 2V, respectively. The barrier between the two gases is removed, and the two gases mix. Heat and work are not exchanged with the surroundings. Since the two gases start at the same temperature and pressure, the temperature and pressure must not change during mixing. What are delta U, delta H, and delta S for the system after...

B. Two distinguishable monatomic ideal gases A and B are held in a volume V by a movable partition of zero weight and volume. The relative proportions of A and B are arbitrary as the system is in equilibrium (i.e., the pressure P and temperature T are uniform throughout the system). Let N = N , +N be the total number of molecules and let x be the fraction of speed or (NB = XN). (a) Calculate the change in...

Consider n moles of ideal gas kept in a heat-isolated cylinder (all processes are adiabatic) with a piston at external pressure p0, and at temperature T0. The external pressure is suddenly changed to p=2p0, and we wait for the system to equilibrate. The volume and the temperature of the ideal gas after equilibration is V and T, respectively. a) Calculate the amount w of work produced on the system in terms of p, p0, V, T0, and n. Using the...

Consider a closed system consisting of one mole of a monoatomic ideal gas X initially at 10.0 atm, a temperature of 487.5 K, and a volume of 4.00 L (state A). From state A, the system may expand isothermally and reversibly to state B, where the pressure is 2.50 atm. The system may also expand adiabatically and reversibly to state B, where the pressure is 2.50 atm. The system may also expand adiabatically and reversibly (through an intermediate state D)...
