Homework Help: A 100-g piece of metal initially at T = 75oC

  1. Oct 25, 2009 #1
    1. The problem statement, all variables and given/known data
    A 100-g piece of metal initially at T = 75oC is submerged in 100 g of water initially at T = 25oC. The specific heat capacity of iron is 0.45 J g-1 °C-1 and the specific heat capacity of water is 4.18 J g-1 °C-1. What is the final temperature of both substances in oC?

    2. Relevant equations
    q=mc(delta T)

    3. The attempt at a solution
    well i tried to set mc(delta T)=mc(delta T), plug in all the values and solve for T(final), but i keep getting the wrong answer

    Can you show your work? It is hard to see what your problem is without being able to check your calculations.
