CHEM 101 Lecture Notes - Lecture 27: Combined Gas Law, Ideal Gas Law, Pennsylvania Route 760
Document Summary
Atm is the force attributed to the weight of air. Sum of individual gas collisions within a molecules attracted to earth by gravity container wall. The height of the mercury column is proportional to. The pressure of a system of gas particles is inversely proportional to the volume of fixed number. Gas change due to condition in which they are found. Changes can be determined empirically using gas laws. Avogadro"s : n and v of moles at constant temperature. The volume of a system of gas is directly proportional to the absolute temperature of fixed number of moles at constant. (p*v)/(n*t)= r ideal gas law constant. Hypothetical gas whose p,v,t properties are accurately described by the ideal gas. 0 o r = 0 k ; 1 o r = 1. 8 k. The units for measuring pressure and volume can vary. in gas calculations these units must agree with those the gas constant. R = 62. 37 l torr mol k.
