Consider a piston-cylinder device (system) that contains 0.06 m3 of air at 300 kPa and 125 ̊C.
(a) If the volume of air in the device increases to 0.15 m3 while the pressure remains constant, determine the work done by the system during the process.
(b) If as a result of heat transfer to the surrounding, the pressure and temperature in the device drop to 240 kPa and 55 ̊C, respectively, and the piston is held such that the volume remains constant, determine the boundary work done during the process.
Consider the system in problem no. 1 above. If the air is compressed to 0.015 m3 in such a way that the temperature inside the cylinder remains constant, and assuming an ideal gas behavior, determine the work done during the proces

Problem 7-173- A piston–cylinder device contains air that undergoes a reversible thermodynamic cycle. Initially, air is at 400 kPa and 300 K with a volume of 0.3 m3. Air is first expanded isothermally to 150 kPa, then compressed adiabatically to the initial pressure, and finally compressed at the constant pressure to the initial state. Accounting for the variation of specific heats with temperature, determine the work and heat transfer for each process.
