Question

What is density with an example?

Answer 1

Density:

• The mass of an object per unit volume is measured as its density.
• An object's average or absolute density is determined by dividing its whole mass by its total volume.

Units of density:

• Density measures the tightness of a material.
• It is denoted by D or $\mathrm{\rho }$.
• Its formula is; $\mathrm{\rho }$=$\mathrm{m}/\mathrm{V}$.
• Where $\mathrm{\rho }$ denotes density, m denotes object mass, and V denotes object volume.
• Although the SI unit of density is$\mathrm{Kg}/{\mathrm{m}}^3$, for convenience we use, $\mathrm{g}/\mathrm{ml}$ it for liquids, $\mathrm{g}/\mathrm{L}$ gases, and $\mathrm{g}/{\mathrm{cm}}^3$ for solids.
