Abstract
ANDRADE1 has derived the expression for the viscosity (η) of a liquid at its melting point in terms of the molecular mass (m), the Lindemann frequency (ν) and the mean molecular distance (σ). This simple relation has been amply substantiated by experimental results and has given us an insight into the mechanism of viscosity in liquids. But so far as we are aware, no equally elegant explanation of the phenomenon of surface tension in liquids has been put forward.
