Mass, Weight, Volume and Density MCQ with Answers

The mass is a matter contained in a body. Mass is expressed in kilogram (kg).

The weight of a body is a force by which it is attracted towards the centre of the earth. Weight is expressed in Newtons (N).

The relation between the mass and weight of a body is given by W = m.g

Density or mass density is defined as the mass per unit volume of a liquid at a standard temperature and pressure. Density or mass density is usually denoted by ρ(rho).

Density or mass density is expressed in kg/m³.

Mathematically, density or mass density, ρ=m/V, where
m = Mass of the liquid, and
V = Volume of the liquid.
