प्रश्न
Distinguish between density and relative density.
उत्तर
| Density | Relative Density |
|
1. It is the ratio of mass to volume. D=`("Mass" )/("Volume")`=`m/v` |
It is the ratio of the density of a substance to the density of water. |
| 2. Units are g `cm^-3` or kg `m^-3` | It is a pure quantity. It has no units. |
| 3. Density in kg ` m^-3`=R.D × 1000 |
R.D = Density in g `cm^-3` R.D=`("Density in kg" cm^-3)/1000` |
