The thermal conductivities of certain liquids

Abstract

The determination of the thermal conductivity of liquids and the variation with temperature has received the attention of a number of workers in the past, notably, Lees in 1898, R. Weber in 1903, and Goldschmidt in 1911. In general, however, the temperature ranges explored were somewhat restricted, and the present work was accordingly directed to determining the conductivities of a number of the more common liquids up to the highest temperatures feasible. In measuring the thermal conductivity of a liquid it is, of course, essential that convection effects should be reduced to a minimum. This may be effected by employing small temperature differences across a thin horizontal layer of the liquid, the heat flow being directed downwards.
