Abstract
We have measured the critical exponent y characterizing the divergence of the viscosity eta |T Tc|^-y for carbon dioxide and xenon. The values of y for both fluids fall within the range y = 0.041 ± 0.001 and are consistent with the range y = 0.042 ± 0.002 spanned by our earlier data for four binary liquid mixtures. This agreement is the strongest evidence that pure fluids and binary liquids are in the same dynamic universality class; however, the results for y are inconsistent with the recent theoretical value of 0.032.Citation
