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.

Solution Summary: The author explains the floating nature of a substance in fluid based on the densities of the substance and the fluid in which it is placed.
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.
