Q2. A 2 lb of steam, initially at 700 lbf/in.², 550°F undergoes a polytropic process in a piston- cylinder assembly to a final pressure of 2200 lbf/in. Kinetic and potential energy effects are negligible. A. show the process on a p-v diagram B. using data from the steam tables, determine the work and heat transfer, in Btu, for a polytropic exponent of X2. X2 = 1.5 C. is assuming ideal gas behavior suitable for the given thermodynamic process? Why?
