Document Summary

Gases expand to fill their containers and assume the shape of their container s. Diffuse into one another and mix in all proportions. 4 properties determine the physical behaviour of gases: amount of gas in moles, volume, pressure, temperature. Atm ( standard atmosphere) - pressure exerted by a mercury column of exactly 760 mm in height when the density of mercury is 13. 59 g/cm^3. Boyle"s law: for a fixed amount of gas at the constant temperature , the gas volume is inversely proportional to the gas pressure. If the weight on the piston is doubled then the pressure is doubled and the volume decrease to its original. Gas properties depend on temperate and pressure. Standard temp = 0 c or 273. 15k, standard pressure: 1 atm (stp) Charles law: the volume of a fixed amount of gas at constant pressure is directly proportional to the kelvin (absolute) temperature.

At constant pressure, the mean free path (λ) of a gas molecule is directly proportional to temperature. At constant temperature, λ is inversely proportional to pressure. If you compare two different gas molecules at the same temperature and pressure, λ is inversely proportional to the square of the diameter of the gas molecules. Put these facts together to create a formula for the mean free path of a gas molecule with a proportionality constant (call it R_mfp, like the ideal-gas constant) and define units for R_mfp
