When compressed liquid properties are unavailable for a substance, it is acceptable to use the ____ values at the same temperature

Select one:

a. saturated liquid

b. saturated vapour

c. critical

d. triple line

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.

A gas decomposes to hydrogen and a liquid in a compressed cylinder of 16 liters. Assuming 298 K, find the maximum pressure the cylinder can withstand (ie, the pressure of hydrogen gas). Formula: 5A(g)-> 2B(l)+ 4H2(g) Mass of A initial: 2000 g Molar Mass of A: 30 g/mol Molar Mass of B: 70 g Density of B: 600 g/mL If you can't assume Ideal Gas, how would one do this with Vapor Pressures?

Why can the physical properties of an unknown substance be used to determine the identification of the substance? Design an experiment to determine if your salt is hygroscopic, deliquescent, efflorescent, or none. Note: this design does not need to be exactly what is followed in the lab. For full credit, a conscientious effort must be shown in your design.
