The surface tension is giver by δ=U
A-TSU
A where
UU
A is the surface energy and SU
A is the surface entropy. In the present paper we calculate SU
Astatistically on the basis of very simple molecular model. The experimental formulae have been given by many authors and one of them, written by Eoivos, is δV
2/3=Κ (TU
0-T), and if V is taken as molan volume, Κ becomes nearly 2.1 erg/degree.
Our result is good agreement with this, though it becomes temperature dependent.
