Document Summary
Volume of a given mass (fixed # of moles) of gas held at constant t varies inversely with the pressure. Volume of a given mass (fixed # of moles) of gas held at constant p is directly proportional to its kelvin temperature. Pressure of a given mass (fixed # of moles) of gas in a constant volume is directly proportional to its kelvin temperature. 14. 2 combined gas laws and avagadro"s principal. Equal volumes of gases at same t and p contain equal numbers of particles. Volume occupied by one mole of gas at 0. 00 c and 1. 00 atmosphere pressure. T, p conditions known as stp standard temperature and pressure. At stp, 1 mole of any gas occupies 22. 4 l. All gases have same keavg at a given t: t constant, ke constant. Relationship between pressure p, volume v, kelvin temperature t, and number of moles n. R = gas constant value depends upon units used for p, v, t.
