What is the difference between the density and relative density of a substance ?
उत्तर
| Density | Relative density |
| The density of a material is its mass per unit volume. | Relative density of a substance is the ratio of density of a substance to the density of water. |
| `ρ = m/V` | `RD = "ρsubstance"/"ρwater"` |
| SI unit of density is kg/m3. | Relative density is a dimensionless quantity. |
