EXAMPLE 6-11 Applying the Ideal Gas Equation to a Mixture of Gases What is the pressure, in bar, exerted by a mixture of 1.0 g H2 and 5.00 g He when the mixture is confined to a volume of 5.0 L at 20 °C? Analyze For fixed T and V, the total pressure of a mixture of gases is determined by the total number of moles of gas: Ptot = ntotRT/V. Solve ntot = (1.0g Hz x 1 mol Hy)...

02) Consider a hydrostatic system represented by the thermodynamic variables volume V, pressure P and temperature T. a) Consider entropy S = S(T, V) and derive the equation TdS. Tas = Cvat +T (1) dV. V Show that this equation can be written as follows BT TdS = CydT + PDV where Cv is the thermal capacity at constant volume, B is the isobaric expansiveness and K is isothermal compressibility: b) Consider a gas described by the equation of state...

A process has been proposed whereby an ideal gas is taken from P=10 bar and T=300 K to P=1 bar and T=500K in a closed system. During the process the system performs 1,000 [J] of work and receives 6,430 [J] of heat from the surroundings at a constant temperature of 300 K. The constant pressure heat capacity of the gas cp=30 [J/(mol K)] . Gas constant R=8.314 [J/(mol K)]. (a) (7 pts.) What is the change of molar internal energy...
