Five grams of the specified pure solvent is placed in a variable volume piston. What are the molar enthalpy and total enthalpy of the pure system when 50% and 75% have been evaporated at (i) 30C, (ii) 50C. Use liquid at 25C as a reference state. a) Benzene (liquid density = 0.88 g/cm3) b) Ethanol (liquid density = 0.79 g/cm3) c) Water without using the steam tables (liquid density = 1 g/cm3) d) Water using the steam tabless

Consider the following experiment with 100 grams of a pure substance in a variable-volume cylindrical container. The base of the cylinder is 100 cm2. The height of the piston from the base of the cylinder is denoted by h (cm). Therefore, the internal volume of the cylinder in cm3 is 100h. The cylinder height is slowly changed and the following data is gathered at equilibrium. case height, h (cm) Number of phases Mass of vapor Temperature (C) 1 3.77 2...
