The straight lines representing the conductivities of the liquids of a homogeneous series (e.g.CnH2n+2) or of a homogenous group (e.g.methane chloro-fluorides) are converging. Their prolongation leads to a zero fictious conductivity, at an absolute temperature twice, the boiling temperature for the non too viscous liquids (smaller than 6 or 7 millipoises at 273°K, and at 2,5 E for the more viscous liquids, acids, alcohols (mean viscosity greater than 6 or 7 millipoises at 273°K. Both these laws permit to express the conductivity of whatever liquid of a series, by the simple relation: T = Y (2E-T)/(2E-X) W.m2.°C, T , conductivity, E, boiling temperature, Y and X, ordinata and abscissa of the converging point.
