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.

Question

Recirculated air from the indoor space is 7,500 cfm (75 degrees F dry bulb, 50% RH). Ventilation air from outdoors is 2,500 cfm (95 degrees F dry bulb, 76 degrees F wet bulb).
