Résumé :

The surface tension of methane has been measured from 91 to 116°K while the surface tension and the molar volume of krypton have been measured from 116 to 122°K. The surface tension of five Kr-CH4 mixtures was also determined, showing an excess surface tension of about -0.45 dyn/cm at 116°K for an equimolecular mixture. (Incidentally the molar volume of the Kr-CH4 mixtures was shown to be additive). The molecular theory of surface tension proposed by Englert-Chwoles and Prigogine predicts an excess surface tension nearly twice as high as the observed value. © 1957.
