14.56: a) The volume displaced must be that which has the same weight and mass as the ice, 3 cm gm 00 . 1 gm 70 . 9 cm 70 . 9 3 = (note that the choice of the form for the density of water avoids conversion of units). b) No; when melted, it is as if the volume displaced by the gm 70 . 9 of melted ice displaces the same volume, and the water level does not change. c) = 3 cm gm 05 . 1 gm

Unformatted text preview: 70 . 9 cm 24 . 9 3 d) The melted water takes up more volume than the salt water displaced, and so 3 cm 46 . flows over. A way of considering this situation (as a thought experiment only) is that the less dense water “floats” on the salt water, and as there is insufficient volume to contain the melted ice, some spills over....
