Expert Solution

Hey, the answer is "Option a. Saturated Liquid".

Explanation: If you ever discover that the substance is in a compressed-liquid state but, you
don't have a compressed table to find the desired thermodynamic values then, all you have to do is use compressed-liquid approximation and assume that the properties of compressed liquid are same as those of the Saturated Liquid at the same temperature.

Specific Internal Energy of compressed Liquid (T, P) ? Specific Internal Energy of Saturated Liquid (T).
Specific Volume of compressed Liquid (T, P) ? Specific Volume of Saturated Liquid (T).
Specific Entropy of compressed Liquid (T, P) ? Specific Entropy of Saturated Liquid (T).
Specific Enthalpy of compressed Liquid (T, P) ? Specific Enthalpy of Saturated (u_f(T)+P*v_f(T)).

u_f(T) = Specific Internal Energy at required Temperature.
P*v_f(T) = (P = P_sat, v_f(T) Specific Volume at required Temperature).

Note: If your desired value falls between two different values then, you might have to use Linear Interpolation to calculate it out.
