Calculate the specific Internal Energy change from the state 1 at (293K;0.45m3kmol1) to state 2 at (303K;42m3kmol1). In your calculation use the specific heat at constant pressure cV=2T+950 with T in [K] and cV in [Jmol1K1] and the Equation of State P=(RT)/(v(bT2)) with b =(vcrr3) where vcr is the critical volume with value 9.41105m3mol1
