The amount of credit given (full or partial) depends on how well you follow these instructions. Unsupported results will not receive credit. 2. 1.974 lbm of ammonia undergoes an isothermal process at 40F from 40 psi initial pressure to a final volume of 0.0500 ft. a. Find the volume (ft) at the initial point and the pressure (psi) at the final point. Sketch this process on the P-v diagram below, clearly indicating the initial and final points. Show explicitly how you found these points. (10 points) b. Find the change in internal energy of this process. (5 points) c. If the heat transfer for this process is 1141.7 kJ out of the system, find the work. (5 points)
