Hi
I'm having a test in physics in school tomorrow and would need some help on the following problem:

Two fluids with knows temperatures and known capacity (or whatever it is called. C anyway) are poured together and after a while they have the same temperature.
How can one calculate that temperature?

First calculate the total energy, which is the sum of $$T \times C$$ for each fluid. Then you say that they end up with the same temperature so you have to solve
$$E = T ( C_1 + C_2 )$$

where E is the total energy and the C's are the two heat capacities and here T is the temperature they end up at (which you are trying to determine).
