100 kg of a certain gas is contained within a piston-cylinder assembly. the gas undergoes a processwhich the pressure volume relationship is (PV)^n = constant. The initial pressure is 6 bars, the initial volume is 0.2 cubic meters ,and final volume is 0.4 cubic meters. the change is specific internal energy of the gas is -10.5 KJ/Kg. determine the following factors ( Hints: KE=PE=0, 1bar=100,000 N/sq.m, 1KJ=1000N.m, 1N= 1Kg.m/sq.sec, W = (p1v1)ln(v2/v1), or W= (p2v2-p1v1)/(1-n) )

(a)find the final pressure in bar for n=2.5

(b) Find the work in KJ for n=2.5

(d) find the net heat transfer for the process for n=2.5 in KJ

(e) sketch the P-V diagram for work done by at n=2.5
