Unformatted text preview: 1 Chapter 10 Gases Gases Gases Characteristics of Gases Unlike liquids and solids, they Expand to fill their containers. Are highly compressible. Gases Are highly compressible. Have extremely low densities. Pressure is the amount of force applied to an area. Pressure Gases Atmospheric pressure is the weight of air per unit of area. P = F A Units of Pressure Pascals 1 Pa = 1 N/m 2 Ba Gases Bar 1 bar = 10 5 Pa = 100 kPa Units of Pressure mm Hg or torr These units are literally the difference in the Gases heights measured in mm ( h ) of two connected columns of mercury. Atmosphere 1.00 atm = 760 torr Manometer Used to measure the difference in pressure between atmospheric Gases pressure and that of a gas in a vessel. 2 Standard Pressure Normal atmospheric pressure at sea level. It is equal to Gases It is equal to 1.00 atm 760 torr (760 mm Hg) 101.325 kPa 1.00 atm = 760 torr (760 mm Hg) = 101.325 kPa Boyles Law The volume of a fixed quantity of gas at constant temperature is inversely proportional to the pressure. Gases As P and V are inversely proportional A plot of V versus P results in a curve....
