Specific Heat Capacity of aluminum rivets

  1. Sep 14, 2012 #1
    1. The problem statement, all variables and given/known data

    Some aluminum rivets of total mass 170 g at 100°C are emptied into a hole in a large block of ice at 0°C'
    a. What will be the final temperature of the rivets?
    b. How much ice will melt?

    2. Relevant equations
    none


    3. The attempt at a solution
    Please help me answer that, i don't know how to solve it....

    Use the formula heat lost by aluminium rivet = heat gained by the ice.

    1) If the block of ice is very big the final temperature of the rivets will be close to zero as all the energy in the hot rivets will be dissipated.

    2) See the reply by rl.bhat and read up on the "specific heat capacity" of aluminium and the "Latent heat Capacity" of water/ice.

    please explain to me why the answer in the first question is zero?
    Thanks..

    You can look at it this way. When the aluminum rivets are emptied into that hole of ice, their temperature goes down to zero and during that process, energy is released which melts some of the ice. When the rivets are cooled down to zero, there is no further decrease in temperature and what you are left with is ice and the rivets at zero degrees.
