Need check on temperature (calorimeter) Problems

  1. Dec 16, 2007 #1
    1. The problem statement, all variables and given/known data

    This is the final graded assignment before finals, and I want to end on a high note and get all of these right.

    "See the Picture Attachment"

    2. Relevant equations

    Teacher said that [tex]\sum[/tex][tex]\Delta[/tex]Q= 0 ---- so ----
    0= Mass(object1)*SpecificHeat(object1)*(Thermal Equilibrium Temp. - Original Heat)
    So I used this type of equation for each question.

    3. The attempt at a solution

    I am going to post my answers and if you don't think they are right say something and then I will explain what I was trying to do, because they are algebra intensive questions.

    1. 20 degrees C

    2. 39.3 degrees C

    3. 84.65 degrees C

    4. .0507

    5. .0335

    6. 45.05 degrees C
