Here are the definitions for the terms requested: Volume: Volume is the amount of three-dimensional space occupied by a substance or object. It is measured in cubic units such as cubic meters (m³). Density: Density is a measure of how much mass is contained in a given volume. Mathematically, it is mass divided by volume, with units like kilograms per cubic meter (kg/m³). Charge Density: Charge density refers to the amount of electric charge per unit measure of space. Specifically, volume charge density is the amount of charge per unit volume of space, denoted by the symbol ρ (rho). It quantifies how electric charge is distributed within a volume. Volume Charge Density (of Charge): Volume charge density is defined as the total electric charge Q divided by the volume V over which the charge is distributed:
ρ=QV\rho =\frac{Q}{V}ρ=VQ
Its SI unit is coulombs per cubic meter (C/m³). It describes how much electric charge is present in a unit volume of a material or space.
