A single ice cube with mass 9.70 g floats in a glass completely full of 420 cm3 of water. You can ignore the water's surface tension and its variation in density with temperature (as long as it remains a liquid).
(a) What volume of water does the ice cube displace?
(b) When the ice cube has completely melted, has any water overflowed If so how much? If not, explain why this is so.
(c) Suppose the water in the glass had been very salty water of density 1050 kg/m'. What volume of salt water would the 9.70-g ice cube displace?
(d) Redo part (b) for the freshwater ice cube in the salty water.
