Question

How will you account for _ density of a substance in the solid state is more than in the liquid state

Answer 1

Molecules of a solid are extremely tightly packed with very strong intermolecular forces of attraction.As density (mass/volume) is the characteristic property of a substance and is determined by how closely the atoms and molecules are packed in a certain volume of the substance,the density of a substance in the solid state is greater than the liquid state, whose molecules are loosely packed and can slide over one another.
