Question

Name two physical quantities that are used to find the density of a substance. write the formula to find the density of a substance.

Answer 1

1. Density: It defines how the molecules of a substance are closely packed with each other.
2. Two physical quantities that are essential to finding the density are Mass and Volume.
3. If $m$ is the mass and $V$is the volume of a substance then the density $\rho$will be
4. $Density\left(\rho \right)=\frac{Mass\left(m\right)}{Volume\left(V\right)}$
5. Its S.I unit is$\frac{kg}{m^3}$.
