Homework Help: Unknown SPecific Heat Capacity

  1. Mar 4, 2010 #1
    1. The problem statement, all variables and given/known data
    In order to find the specific heat capacity of an unknown material,
    a 50g piece is heated to 80 degrees Celsius and fully immersed in a well
    insulatyed calorimeter filled with 100g of water at 10 degrees Celsius raising the temperature of the water by 5 degrees, the heat capacity of the calorimeter is 20 J K-1

    2. Relevant equations
    MC delta T = MC delta T ?

    3. The attempt at a solution
    no idea to be honest
    at first i thought i can just use Q=mc delta T to do this but i dunno what Q is :S

    The final temperature of substance is same as that of water. You could still use the eqn. you wrote.
