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
I have solved the question
step by step and neatly so that you can understand the solution
easily and quickly. Please dear thumpsup for the work. Thank
you.

Assuming ideal gas behavior for the air, determine the mass in kg.
Can someone help me with this thermodynamics problem? A piston‐cylinder assembly contains 1.5 lb of air initially at 80°F and 1 atm. The air undergoes a constant‐pressure process during which the rate of heat transfer from the air is 4 Btu/h resulting in a final air temperature of 40°F. Assuming ideal gas behavior with k = 1.4 and negligible effects of kinetic and potential energy for the air, determine the time, in minutes, associated with the process.

Problem 3.052 A piston–cylinder assembly contains 2 lb of water, initially at 100 lbf/in.2 and 450°F. The water undergoes two processes in series: a constant-pressure process followed by a constant volume process. At the end of the constant-volume process, the temperature is 300°F and the water is a two-phase liquid–vapor mixture with a quality of 40%. Neglect kinetic and potential energy effects. Determine the work and heat transfer for each process, all in Btu.
