Question

The density of _______ does not change much with a change in temperature.

Answer 1

1. Density: Density, is the substance's mass per unit of volume. It defines how closely the molecules are packed with each other in substances.
2. If $m$ is the mass and $V$ is the volume of a substance then its density $\rho$ is
3. $Density\left(\rho \right)=\frac{Mass\left(m\right)}{Volume\left(V\right)}$
4. Its S.I unit is $\frac{kg}{m^3}$.
5. In the case of solids, if we increase the temperature then mass doesn't change and volume gets slightly changed so there will be a negligible change of density in solids.

Hence, the density of solids does not change much with a change in temperature.
