dalton s notation.
in 1801, john dalton published law of partial pressures work ideal gas law relationship: pressure of mixture of non reactive gases equal sum of pressures of of constituent gases alone. mathematically, can represented n species as:
pressuretotal = pressure1 + pressure2 + ... + pressuren
the image of dalton s journal depicts symbology used shorthand record path followed. among key journal observations upon mixing unreactive elastic fluids (gases) following:
unlike liquids, heavier gases did not drift bottom upon mixing.
gas particle identity played no role in determining final pressure (they behaved if size negligible).
