Quite URGENT: Temp change equation needed when u add cold water to hot water Watch
Ya I know Thermal conductivity of water, volume of the cold water and hot water, density, specific heat capacity
so any equations to link all those so that I get a equation that will generate the decrease in temp?
energy change = constant x no. of molecules x temp change
E = knt
I get T3 = [d1V1cT1 + d2V2cT2]/[d1V1c + d2V2c]
1 = cold water, 2 = hot water, 3 = after mixing
and d=density, V = volume, c = spec. heat. capac. and T = temp.
thermal conductivity doesnt come into it, because at both times the temperature is in equilibrium
