Homework Help: Specific heat

  1. Jul 22, 2009 #1
    1. The problem statement, all variables and given/known data

    Given that ice has a specific heat that is half of that of water, does it take more thermal energy to raise the temperature of 5 grams of water or 5 grams of ice by 6 degrees Celsius?

    2. Relevant equations

    Q=mc delta t

    3. The attempt at a solution

    So I think it takes more energy to raise the temperature of water. Am I right? The answer given is ice, could that just be a mistake?

    If you assume the temperature of the ice is zero degree, the ice takes more energy to melt and then rise the temperature. Where as the water directly rises the temperature.
