Question

Explain density in simple words.

Answer 1

Density

• Density is a measure of how compact the mass in a substance or object is.
• Mathematically, it is represented by the equation

$\mathrm{Density}=\frac{\mathrm{Mass}}{\mathrm{Volume}}$

Density is a measure of mass per unit of volume.

• In general, gases have the lowest densities, and solids have the highest but these densities are highly dependent on the pressure and temperature.
• The density range of solids is quite wide.
• There is no regular trend in the density across the periodic table.

Metals have the highest densities as their atoms are closely packed, although that of lithium, the highest metallic element, is quite low.
