Answer: The correct option is (4).
Explanation:
Density of a substance is defined as measure of mass per unit volume.
- It is calculated by dividing given mass of the substance from its given volume, \(density=\frac{\text{mass of the substance}}{\text{volume of the substance}}\).
- S.I unit of density is kilogram per meter cube (\(Kg/m^3\)).
- Higher the value of density, the more mass is concentrated in a unit volume of the substance. Substance will said to be denser.
- Lower the value of density, less mass is concentrated in a unit volume of the substance. Substance will said to be less denser.
