1 Zumdahl Chapter 5 Gases General Properties: 1. They uniformly fill any container 2. They are compressible 3. They mix in almost all proportions 4. They are less dense than liquids and solids 5. They exert Pressure . 1.Measurements of Pressure: • Gas molecules exert pressure . Atmospheric pressure Pressure exerted by the air. • Atmospheric pressure over a given area pressure of the column of air above it. = A F P The barometer: instrument for measuring atmospheric pressure. The atmospheric pressure balances that of the column of mercury. At sea level, and 0 ° C, h = 760 mm.
