The refrigerant R-410a is contained in a piston-cylinder device, as shown in the figure, where the volume is 13 L when the piston hits the stops. The initial state of the fluid is -30 °C, 150 kPa, with a volume of 10 L. The entire system is brought indoors and warms up to 25 °C.
A) Is the piston at the stops in the final state?
B) Find the total work done by the R-410a during the process.
