Thermal energy homework help?

  1. Mar 7, 2015 #1
    MODERATOR NOTE: MISPLACED HOMEWORK, SO NO TEMPLATE

    When filling up the tub for a bath, only the hot water tap was turned on. After realizing the mistake after a minute with half the tub at 60 C, how much cold water (as fraction of the whole tub) at 9 C must be added such that the final temperature of the water is 36 C?

    Would the solution have to do with the equation mct=-mct?

    Thanks in advance!

    If you fix the symbols there (are the mct on the left and right side the same thing?) and write down what they mean, you can use this formula, yes.
