The Law of Corresponding States as Applied to Sound Velocity in Liquids Consisting of Elliptical Molecules

Abstract

The velocity of sound was measured in liquid ethane, under saturated vapor, in the normal liquid range by a resonance technique.With the use of existing velocity data for argon, nitrogen, and oxygen, a modified form of the corresponding-states principle was applied to the elliptical molecules, oxygen, nitrogen, and ethane. Good correspondence was found for reduced temperatures less than one (T* < 1).
