help please! i don't know how to use the pressure volume relation in this problem.
A fluid system undergoes a nonflow frictionless process following the pressure volume relation as P = (5/V) + 1.5 where P is in bar and V is in m3. During the process the volume changes from 0.15 m3 to 0.05 m3 and the system rejects 45 kJ of heat. Determine:
A] change in internal energy
B] change in enthalpy
