3 moles of an ideal monatomic gas are compressed reversibly and isothermally from an initial volume of 500 l at 30° C to a final volume of 50 l. Calculate: (a) the initial and final pressure of the gas, and (b) ΔQ , ΔW, ΔU, ΔΗ for the compression.
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...

1. a) One mole of an ideal gas is compressed irreversibly from 2 L to 1 L under a constant external pressure of 5 atm. The temperature is 300 K. Calculate the work done on the gas during the compression. b When the gas is cooled to sufficiently low temperatures, it is found experimentally that the equation of state for the gas no longer resembles the ideal gas law. Instead, what is found is that...
