In the process represented in the figure, 2.4 moles of an ideal monatomic gas start at state a, with pressure 1 atm (1.01*10^5 N/m^2) and volume 5.8*10^-2 m^3 . The pressure at states b and c is twice the original pressure, and the volume at states c and d is twice the original volume. The gas constant R=8.134 J/mol*K.
