Archimedes principle explained

  1. Dec 22, 2006 #1
    Can somebody explain Achimedes principle to me? Where he used it to determine the difference in density between silver and gold. Apparently he immersed a lump of gold and silver in water (I assume they were the same size/volume) and each lump displaced a different volume of water. Is that the correct story? If it is, how can two objects with the same volume displace a different amount of water?????

    The pieces of gold and silver did not have the same volume, they had the same mass.

    The silver is obviously less dense, therefore has a greater volume, therefore displaces more water.

    That's what I thought. Thanks
