The authors’ experiments on the thermal conductivities of carbon monoxide and nitrous oxide were undertaken partly because very few determinations had been made previously, and partly on account of a consideration of other physical properties of these gases. Smith showed experimentally that the viscosities of nitrogen and carbon monoxide are equal, and a similar result was obtained in the case of carbon dioxide and nitrous oxide. Such results are indicated by the Kinetic Theory of Gases from the aspect of the equality of molecular weights in the two cases. Similar equalities are not anticipated, however, in the case of the thermal conductivities, as the conduction effect depends on a consideration of differences in molecular structure. The following table shows the values of the thermal conductivities and the viscosities of the four gases concerned, and illustrates the extent to which the thermal conductivities differ:—
