Abstract

The asymptotic critical behavior of the thermal diffusivity of H2O, deduced from dynamic light-scattering measurements, is shown to be in good agreement with the mode-coupling theory for critical dynamics in fluids. Consistency of the thermal-diffusivity measurements with the critical enhancement of the viscosity of H2O is also demonstrated.
