ON THE RELATIONSHIP BETWEEN FLUIDITY OF LIQUIDS AND TEMPERATURE

Starting from Batschinski's equation an equation relating fluidity (φ) with the coefficient of thermal expansion (α) of a liquid has been derived which gives a linear plot for φ against e*t. This relationship has been verified in the case of as many as 6o different liquids From the intercept of the graph on the e*t —axis, demensions of molecules have been calculated and compared with the values obtained from other methods Members of the same homologous series are found to yield the same intercept in each case as has been verified with five different homologous series
