+m=3;//Mass of substance in the system in kg

+P1=500;//Initial pressure of the system in kPa

+P2=100;//Final pressure of the system in kPa

+V1=0.22;//Initial volume of the system in m^3

+n=1.2;//Polytropic index 

+Q1=30;//Heat transfer for the another process

+

+//Calculations

+V2=V1*(P1/P2)^(1/1.2);//Final volume of the system in m^3

+U=3.56*(P2*V2-P1*V1);//Total change in internal energy in kJ
