Consider a piston-cylinder system with an initial volume of 0.04 m3 at 200 kPa. Calculate the work being carried out to increase the volume to 0.1 m3 for each of the following processes (drawing diagrams P - V for each case):
a) A burner is placed and the volume increases at constant pressure
b) The weights are removed so that PV = constant
c) The weights are removed so that PV1.3 = constant
d) It cools at constant volume until a pressure of 100 KPa.
