ABSTRACT
The capillary method of surface tension measurement has been used to measure the surface tension of oxygen nitrogen solutions in the temperature range from80 to 132 K. At temperatures belowthe nitrogen critical temperature (Tc = 126.2 K) the capillary constant and the surface tension of solutions are smaller than their additive values and vary linearly with the temperature. Experimental data are compared with the results of calculating the surface tension by the theories of Pinnes and Rowlinson.
