A modification of the dilatometer method for measuring the density of liquids which can be applied over a large temperature range and up to the region of the critical temperature is described. The densities of methyl ether and propylene have been measured over the temperature range 7°–120 °C. and 20°–88 °C. respectively, with an accuracy of 1 part in 2000. A comparison is made with the data of other investigators. Application of the data to the law of corresponding states shows that the law holds to within the accuracy attained up to temperatures at least 0.96 of the critical.

Measurements have been made by determining the force necessary to break the liquid film between the edge of a suspended metal ring and the liquid surface. The results obtained are about 13% larger than those given by Allen and Misener (1938), and the variation of the surface tension, γ, with temperature T fits quite well the equation γ = 0.600 (1 − T/Tc)1.04 dyne cm−1, where Tc is the critical temperature. Comparison with other liquids has been made following de Boer's formulation of the law of corresponding states, and the reduced equation γ = (γ0*/Tc*n) (Tc* − T*)n describes the results, (γ0*/Tc*n) and n being functions of the quantum parameter Λ*; the classical limit of (γ0*/Tc*n) is found by extrapolation to be 2.2.
