The data below of an unnamed fluid Z.

a) Calculate the residual entropy of the saturated liquid.

b) Calculate the entropy at 10 bar, 393.15 K, using as reference state the ideal-gas state at 393.15 K, 1 bar.

c) Calculate the internal energy at 10 bar, 393.15 K, using as reference state the ideal-gas state at 393.15 K, 1 bar.

d) The fluid expands in closed system by reversible isothermal process from 393.15 K, 10 bar, until it forms a vapor-liquid mixture that contains 30% by mol liquid. Determine the amount of heat.
