Calculate the specific Internal Energy change from the state 1 at (293 K; 0.45 m³ kmol–1) to state 2 at (303 K; 42 m³ kmol–1). In your calculation use the specific heat at constant pressure cv = – 2 T + 950 with T in [K] and cv in [J mol –1 K–1] and the Equation of State P = (R T)/(v – (b T2)) with b = (vcr/3) where vcr is the critical volume with value 9.41 x 10 –5 m³ mol –1.
