Explain the concept of density
WebUnit of Density. Though the SI unit of density is kg/m³, for convenience we use g/cm³ for solids, g/ml for liquids, and g/L for gases. Density can be explained as the relationship between the mass of the substance and the volume it takes up. In a qualitative term, it shows how much heavy an object is at constant volume. WebDensity (volumetric mass density or specific mass) is the substance's mass per unit of volume.The symbol most often used for density is ρ (the lower case Greek letter rho), …
