Properties of Pure Substances

A substance with fixed chemical composition throughout is called a pure substance like water, air, and nitrogen. A pure substance does not have to be a single element or compound. A mixture of two or more phases of a pure substance is also a pure substance as long as the chemical composition is the same for all phases. These substances mainly have a constant/ uniform composition. The substances also have fixed boiling and melting points. A pure substance takes part in a chemical reaction to form predictable products.

A rigid, well-insulated tank contains a two-phase mixture of ammonia with 0.0022 ft³ of saturated liquid and 1.5 ft3 of saturated vapor, initially at p₁ = 70 lb/in². A paddle wheel stirs the mixture until only saturated vapor at higher pressure, p2, remains in the tank. Kinetic and potential energy effects are negligible. Determine the pressure p2, in lb/in², and the amount of energy transfer by work, in Btu. Step 1 * Your answer is incorrect. Determine p2, in lb/in². P2= i81.56 lb/in²
Need help with these two homework problems 1) A tank contains a two-phase liquid–vapor mixture of Refrigerant 22 at 8 bar. The mass of saturated liquid in the tank is 25 kg and the quality is 30%. Determine the volume of the tank, in m3, and the percentage of the total volume occupied by saturated vapor. 2) One kilogram of water contained in a piston–cylinder assembly, initially saturated vapor at 100 kPa, is condensed at constant pressure to saturated liquid. Consider an enlarged system consisting of the water and enough of the nearby surroundings that heat transfer occurs only at the ambient temperature of 25oC. Assume the state of the nearby surroundings does not change during the process, and ignore kinetic and potential energy effects. For the enlarged system, determine the heat transfer, in kJ, and the entropy production, in kJ/K.
