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).
