Specific Heat Capacity of metal in water

  1. Dec 9, 2011 #1
    1. The problem statement, all variables and given/known data
    An unknown metal with C=3.6 Mass=150g Temp=160c is added to copper container(85g) filled with water(105g) both with an initial temp of 20c

    I have to find the final temp of water,container and metal



    2. Relevant equations
    none given but I assume it will be E=Cm(t1-t2)


    3. The attempt at a solution

    I'm just going over it at the moment and wanted to know if that is enough information to work out the answer.The wording of the question is a bit vague and i'm not sure if I should be using information from the question that came before.

    Thanks

    You'll be needing the specific heats of water and copper.

    [EDIT:] Also, what are the units associated with the C of the unknown metal?

    Sorry must have missed these off

    Unknown =3.6
    Water =4.2
    Copper =0.4

    You should indicates the units associated with those numbers. Otherwise how is one to know if they are cal/gram/K, J/kg/K, J/mol/K, kJ/kg/K,....
