0.09m cube of a fluid at 0.7bar are compressed reversibly to a pressure of 3.5bar according to law pvn=constant. the fluid is then heated reversibly at a constant volume until the pressure is 4bar, the specific volume is then 0.5mcube/kg a reversibly expansion according to a law pv2=constant restores the fluid to its initial state. compute the mess of the Fluid present, the value of n in the first process, and the networkdone on or by fluid in the cycle
