Correct Answer - Option 4 : Specific volume
Explanation:
Volume V is the space occupied by a substance and the unit of volume is m3.
- Mass per unit volume is called density.
- Volume per unit mass is called a specific volume.
The specific volume of a gas is defined as the volume of the gas in a unit mass of the gas.
i.e. specific volume \(v = \frac{{volume}}{{mass}} = \frac{V}{m} = \frac{{{m^3}}}{{kg}}\)
thus the unit of specific volume is m
3/kg and also the
specific volume is inverse of density (ρ).
