  1. How much heat is availbale in the Al block when changing T from 350 degrees Celsius (note the correct spelling of Celsius) to 0 degrees C.?

    q = mass x specific heat Al x delta T.

    how much heat is used in melting ice?
    q = mass x heat fusion.

    calculate mass.

    Post your work if you get stuck.
