Summary

When lines of constant moisture content (isosteres) are plotted on axes of In r (r, relative humidity) versus In ps (ps, pressure of water vapour at saturation), approximately straight lines result. Other axes with the same property are discussed. The slope of lines of constant Gibbs free energy of water vapour is derived for the above chart and it is shown that the basic equation of sorption is represented by this slope and that of the isostere.
