Consider a system consisting of 3.0 mol CO2(g), initially at 35°C and 9.0 atm and confined to a cylinder of cross-section 100.0 cm2. The sample is allowed to expand irreversibly and adiabatically against an external pressure of 2.5 atm until the piston has moved outwards through 25 cm. Assume that carbon dioxide may be considered a perfect gas with CV,m = 28.8 J K–1 mol–1, and calculate (a) q, (b) w, (c) ΔU, (d) ΔT, (e) ΔS.

P3A.2 A sample consisting of 0.10 mol of perfect gas muICLUL is piston inside a cylinder such that the volume is 1.25 dm'; the external pressure is constant at 1.00 bar and the temperature is maintained at 300 K by a thermostat. The piston is released so that the gas can expand. Calculate (a) the volume of the gas when the expansion is complete; (b) the work done when the gas expands; (c) the heat absorbed by the system. Hence...

For the following processes, calculate the indicated quanti- ties for a system consisting of 1 mol of N2 gas. Assume ideal gas behavior. a. The gas, initially at 10 bar, is expanded tenfold in volume against a constant external pressure of 1 bar, all at 298 K. Calculate q, w, ?U and ?H for the gas. b. After the expansion in part (a), the volume is fixed, and heat is added until the temperature reaches 373 K. Calculate q, w,...

Suppose that we allow 3.50 mol of an ideal gas with Cv=5R/2 to expand isothermally and reversibly from 100 atm, 10 L to 10.0 atm and then the gas is allowed to expand adiabatically and reversibly to a final pressure of 1.00 atm. Calculate q, w, ΔU and ΔH for each step and the total values for the two steps. Suppose now that the processes are carried out irreversibly with pressure dropping discontinuously from 100 atm to 10.0 atm in...
