Four hundred millilitres (mL) of a strong brine solution at room temperature was poured into a measuring cylinder
(Figure 1). A piece of ice of mass 100 g was then gently placed in the brine solution and allowed to float freely
(Figure 2). Changes in the surface level of the liquid in the cylinder were then observed until all the ice had melted.
Assume that the densities of water, ice and the brine solution are 1000 kg m-3, 900 kg m3 and 1100 kg m3,
respectively.
