A piston-cylinder assembly contains air, initially at 60 lbf/in2, 900°R, and a volume of 0.05 ft3. The air undergoes a process to a state where the final volume is 0.10 ft3. The process is polytropic with n=1.4. Assuming ideal gas behavior for the air: a. Draw the process in the p-V diagram and write the engineering model.
a. Clearly label the states and indicate the direction of the process.

b. Determine the mass of the air, in lb
