Imagine a substance with the following points on the phase diagram: a triple point at .5 atm and -5ºC; a normal melting point at 20ºC; normal boiling point at 150ºC; and a critical point at 5 atm and 1000ºC. The solid liquid line is “normal” (meaning positive sloping). For this, complete the following: 1. Describe what one would see at pressures and temperatures above 5 atm and 1000ºC. 2. Describe what will happen to the substance when it begins in a vacuum at -15 ºC and is slowly pressurized. 3. Describe the phase changes from -80ºC to 500ºC at 2 atm.

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.
