When the gas is in state A on the diagram, the pressure is 22.5 atm and the temperature is 600 K. When it is in state C, the pressure is 1.00 atm and the temperature is 400 K. (Note that the diagram is not drawn to scale. Due to the nature of this problem, do not use rounded intermediate valuesincluding answers submitted in WebAssignin your calculations.) The work done during the cycle equals the area enclosed by the path on the PV diagram. 1) @ 22.5 atm | atm 1.00 atm Submit Answer 14.
