When mixing liquids, do the temps average?

Or is there more to it than I don't understand.

Basically if you mix 2 liquids, 5 oz water at 120° and 5oz water at 100° will the resulting 10 oz liquid be 110°?

What about if there's a drastic difference? Say 5oz@50° and 5oz@250°, result 150°?

What if there's a difference in volume? 8oz@200° and 2oz@100°, result 180°?

If it's the same liquids in the same amounts, then the final temperature is the average of the two.  If you have different amounts, then it is the weighted average of the two temperatures.  If you have different liquids, then you need to use the more general formula:

m1c1(Tf-Ti)=m2c2(Tf-Tf)

Where c is the specific heat capacity of each substance.
