Homework Help: Melting ice and water displacement

  1. Nov 29, 2007 #1
    1. My professor gave us an extra credit problem in which we have to prove that water level does not change when ice melts.



    2. (v)ice=(v)displaced water



    3. any ideas?

    Consider Archimedes's principle.

    so i have this:

    Fb=(W) fluid displaced. and for the ice in a glass---- (V)ice=(V)displaced fluid.

    (m)ice above surface=(m)(v of water)-(m)ice below.

    Think of it this way: How much water does a mass "m" of ice displace? (Don't forget that the ice is floating. Use that fact.)
