二理想气体定律( The ideal gas law) 1由来: (1)Boye'shaw:n,T不变vcl/porp= constant (2) Charles'law:n2p不变 V aT or V/T= constant (3) Avogadro'slaw:T,p不变∝n Avogadro's hypothesis Equal volumes of gases at the same temperature a molecular pressure contain equal numbers of molecular Avogadro's law The volume of a gas maintained at constant temperature and pressure is directly proportional to the number of moles of the gas.二 理想气体定律(The Ideal Gas Law) (3) Avogadro' slaw : (2) Charles' law : or constant (1)Boyle'slaw : 1/ or constant 1. T,p V n n,p V T V/T n,T V p pV   =  = 不变 不变 不变 由来： Avogadro’s hypothesis :Equal volumes of gases at the same temperature a molecular pressure contain equal numbers of molecular. Avogadro’s law :The volume of a gas maintained at constant temperature and pressure is directly proportional to the number of moles of the gas
