These questions require more thought and integrate several concepts.

The densities of several elements are given in Table 1.1.

(a) Of the elements nickel, gold, lead, and magnesium, which will float on liquid mercury at 20 °C?

(b) Of the elements titanium, copper, iron, and gold, which will float highest on the mercury? That is, which element will have the smallest fraction of its volume below the surface of the liquid?
