Homework Help: Specific Heat Capacity and Thermal Conductivity

  1. Feb 3, 2010 #1
    1. The problem statement, all variables and given/known data

    To summarize, I am given 6 objects and their corresponding specific heat capacity and thermal conductivity values. All objects have the same mass. The question is asking me to rank the objects based on temperature if they are put in a hot oven until they reach thermal equilibrium and removed.

    2. Relevant equations

    Q=mc[tex]\Delta[/tex]T (specific heat capacity)
    Q/[tex]\Delta[/tex]t=k(A/L)[tex]\Delta[/tex]T (thermal conductivity)

    3. The attempt at a solution

    I initially ranked the objects from lowest heat capacity to highest heat capacity because I was thinking that the objects that require less energy to raise their temperature will be hottest upon removal.
    I'm not really sure how to relate thermal conductivity and specific heat capacity to find out their temperatures after removal... My textbook doesn't help either.

    ...Nevermind. I realized that it doesn't matter what the values for specific heat capacity and thermal conductivity... if the oven is maintained at the given temperature, all objects will be the same upon removal if they are allowed to reach thermal equilibrium.
