    Do you mean the rate of diffusion?

    Ahh, you would simply use the equation for specific heat capacity [itex]\Delta Q = mc\Delta\theta[/itex]. You would have to use simultaneous equations. HINT: The energy lost by the water at 100 degrees must be equal to the energy gained by the water at zero degrees.

    No problem, I was worried for a moment then because I'd never heard of such a formula :confused: :biggrin:
