Homework Help: Initial Temperature

  1. May 10, 2010 #1
    1. The problem statement, all variables and given/known data
    A student doing an experiment pours 0.150 kg of heated copper **** into a 0.375 kg aluminum calorimeter cup containing 0.200 kg of water. The cup and water are both initially at 25 C. The mixture (and the cup) comes to thermal equilibrium at 28 C. What was the initial temperature of the shot?

    2. Relevant equations
    The only equations in the chapter are specific heat:

    Q=cm(delta)T or c=Q/m(delta)T

    3. The attempt at a solution

    No clue

    DeltaT = Tf -Ti

    Qcalorimeter + Qsolution + QWater = 0
