Do you mean the rate of diffusion?

sorry for not beign specific before hand
i mean't the mixture formula of heat difference for subnstances of the same phase

Sorry, I don't quite understand. Do you have a specific example?

umm.....
if i have 1 kg of water at 100 degrees and 10 kg of water at zero, what formaula or series of formulas would i use to to calculate the final temperature

Ahh, you would simply use the equation for specific heat capacity $\Delta Q = mc\Delta\theta$. 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
