Equilibrium temperature

  1. Jul 3, 2008 #1
    When 1 kg of water at 100degC is mixed with 10kg of water at 0degC, the equilibrium temperature will be:
    a)exactly 0degC
    b)exactly 50degC
    c)exactly 100degC
    d)slightly above 0degC

    if anyone can post the formula to use for this that would be great! thanks!

    Welcome to the forum! What thoughts have you had about this problem? Is it part of something you've been doing recently at school etc? Are there any parts you remember from those lessons that may be useful here?

    I'm taking an online course, so it's all self teaching... (it can get a little confusing at times) so i have to find most of the information myself, and this one just doesn't seem to be the same anywhere (or understandable).
    i know that equilibrium is a state of rest or balance due to the equal action of opposing forces, but have no idea how to calculate the temperature...
