Determine the mass specific internal energy (u) of the following two substances

Determine the mass specific internal energy (u) of the following two substances at the given conditions. Also determine which (if either) of these substances can be well-approximated as: 1) a thermally perfect gas at these conditions; 2) an incompressible substance at these conditions; and 3) a calorically perfect substance over the temperature range 250-1000 K (for each of these last three questions, your answer would be Substance 1, Substance 2, both or neither; along with justifications for your responses). Substance p (bar) T (K) p (kg/m) h (kJ/kg) 1 1.00 250. 75.3 1.3 1 30.0 250. 76.3 40.3 1 30.0 500. 73.5 260.8 1 30.0 1000. 67.4 704.5 1.00 250. 2.4 41.2 30.0 250. 68.3 43.9 30.0 500. 1000. 35.5 194.5 30.0 18.0 556.6 N222
