6 kg of a substance undergoes a process from 1.00 MPa, 0.50 m^3 to 500 kPa. During this process the internal enegy decreases by 115 kJ, the kinetic energy decreases by 15 Btu and the potential energy increases by 19 kJ.
a. Find the work in kJ for the path given below.
b. Find the heat transfer for the process in Btu. PV^1.6 = constant
