A frictionless piston cylinder device contains 10kg of nitrogen initially at 200kpa and 27C. the nitrogen is now heated to 77C by supplying .25 KWh of electrical work through a resistance heater (see figure). During this process heat is being lost to the surroundings.

A: redraw the sketch and identify all the heat transfer mechanism relevant this problem.

B: calculate the initial volume of the piston cylinder device (in m^3).

C: Calculate the boundary work in KJ. Explain whether work is being supplied to the system or extracted from the system.

D: calculate the heat transferred to the surroundings In KJ.

E: show the process on a Pressure volume diagram. Locate the initial state, the final state, and the process path with respect to the saturation dome.
