Document Summary

Characteristics: expand to fill their containers; are highly compressible; have extremely low densities. Pressure is the amount of force applied to an area: atmospheric pressure is the weight of air per unit of area. Manometer: device used to measure the difference in pressure between atmospheric pressure and that of a gas in a vessel. Standard pressure: normal atmospheric pressure at sea level. Equal to 1. 00 atm, 760 torr (760 mm hg), 101. 325 kpa. Boyle"s law: the volume of a fixed quantity of gas at constant temperature is inversely proportional to the pressure, pv = k, v = k (1/p) Charles"s law: the volume of a fixed amount of gas at constant pressure is directly proportional to its absolute temperature, v/t = k. Avogadro"s law: the volume of a gas at constant temperature and pressure is directly proportional to the number of moles of the gas, v = kn.
