Q(in) = 5,845 J
W(out) = -5,845 J
A heat engine using a monatomic gas follows the cycle shown in the pV diagram to the right. The gas starts out at point 1 with a volume of 233 cm3, a pressure of 235 kPa, and a temperature of 317 K. The gas is held at a constant volume while it is heated until its temperature reaches 395 K (point 2). The gas is then allowed to expand adiabatically until its pressure is again 235 kPa (point 3). The gas is maintained at this pressure while it is cooled back to its original temperature of 317 K (point 1 again).
For each stage of this process, calculate in joules the heat Q(in) transferred to the gas, and the work W(out) done by the gas.
