According to the numerical resolution to Fourier fluid thermodynamics , the supersolid skin of 3/4 mass density of the standard raises the thermal diffusivity, α ∝ ρ -1 , that promotes the outward heat flow involved in the Mpemba paradox . The Mpemba paradox shows that warm water cools faster when its initial skin temperature is higher than its interior till an equilibrium. Consistency in theoretical and experimental observations (shown in FIG. and) clarified that the Mpemba paradox proceeds in the following stages. The H-O bond absorbs energy through thermal contraction, followed by cooling and energy emission in the reverse, at a rate proportional to its initial storage or bond length deformation. The high thermal diffusivity of the liquid skin leads to rapid heat diffusion crossing the supersolid interface. Therefore, the resolution to the Mpemba paradox evidences the O:H-O bond memorability and water skin supersolidity.
