Explanation:
Detailed explanation-1: -The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). The mass of atoms, their size, and how they are arranged determine the density of a substance. Density equals the mass of the substance divided by its volume; D = m/v.
Detailed explanation-2: -Solids. A solid’s particles are packed closely together. The forces between the particles are strong enough that the particles cannot move freely; they can only vibrate. As a result, a solid has a stable, definite shape and a definite volume.
Detailed explanation-3: -The density of a substance is defined as the mass per unit volume of that substance.
