Solve the given problem:
Problem: Three kg of gas in a piston-cylinder assembly undergo a process during which the relationship between pressure and specific volume is pv 0.5=constant. The process begins with p1=250 kPa and V1=1.5 m3 and ends with p2=100 kPa.
Part A: Determine the final specific volume.
Any help I can get on this problem is greatly appreciated! I'm not too familiar with this problem. Plot the process on a graph of pressure versus specific volume.
