Based on the densities given in table 1.1, among the elements, nickel, gold, lead and magnesium, the element that floats on liquid mercury at 20 ° C has to be given. Concept Introduction: Buoyancy: It explains the floating nature of a substance in a fluid based on the densities of the substance and the fluid in which it is placed. If a substance with low density is placed in a fluid of more density, then the substance floats in that fluid. If a substance with high density is placed in a fluid of low density, then the substance sinks in that fluid.
