A 618 g sample of water at 73◦C is mixed with
478 g of water at 34◦C.
What is the final temperature of the mix-
ture? Assume no heat loss to the surround-
ings.
Answer in units of ◦C.

  • PHYSICS!! -

    final temp t
    Cv = specific heat capacity of fluid
    heat in to lower = 478 * Cv * (t-34)
    heat out of upper = 618 *Cv*(73-t)
    heat into cold = heat out of hot

    478 (t-34) = 618 (73-t)

    solve for t
