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.

E3.1. You must use the property data from the tables in the Appendix of your text to do this problem. The figure below illustrates a pressure cooker with the pressure relief valve removed. atm- 100 kPa V= 2 liter bottom 5% is filled with liquid water . The pressure cooker has an internal volume of V = 2 liters. Because the relief valve is removed, the contents are initially at atmospheric pressure, Patm = 100 kPa. The pressure cooker contains water in a two-phase state. The bottom 5% of the volume of the vessel is filled with liquid water while the remainder of the vessel contains water vapor. a) Determine the initial temperature of the water in the cooker. b) Determine the quality and specific volume of the water initially in the cooker. c) Sketch by hand a T-v diagram and label the initial state of the water (state 1).
