Density and pressure

Need to know

What you need to know

• Density ($\rho$) is the mass ($m$) per unit volume ($V$) of a substance.
• The formula for density is $\rho = \frac{m}{V}$.
• The standard SI unit for density is kilograms per cubic meter (kg m^{-3}).
• Density is an intrinsic property of a material.

Explanation
