A heat engine using a diatomic gas follows the cycle shown in the pV diagram. Adiabat L V (cm') p (kPa) P₁ The gas starts out at point 1 with a volume of V₁ = 233 cm³, a pressure of p₁ = 147 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 147 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 the first stage of this process, calculate in joules the heat Q₁2 transferred to the gas and the work W₁2 done by the gas.
