Question

Explain in detail the derive units - volume, density and temperature. What are derived units?

Answer 1

Derived units $\to$

Derived units are units of measurement derived from the seven base units specified by the International System of Units.

Derived unit of volume:-

Volume is the measure of the amount of space occupied by an object. The standard volume is a cubic meter $\left(m^3\right)$, a cube with an edge length of exactly one meter.

Derived unit of density:-

We use the mass and volume of a substance to determine its density. Thus, the units of density are defined by the base units of mass and length.

The density of a substance is the ratio of the mass of a sample of the substance to its volume. The SI unit for density is the kilogram per cubic meter $\left(kg/m^3\right)$.

Note:- Temperature is not a derived unit. It is an intensive property. The SI unit of temperature is the kelvin $\left(K\right)$.
