Which of the following is the SI unit of specific volume?
Correct Answer: D. m³/kg
Explanation: The correct answer is m³/kg. Specific volume is defined as the ratio of a substance's volume to its mass, which is the reciprocal of density. In the International System of Units (SI), volume is measured in cubic meters (m³) and mass is measured in kilograms (kg). Therefore, the SI unit for specific volume is expressed as cubic meters per kilogram (m³/kg). Unlike density, which indicates how much mass is contained in a given volume, specific volume shows how much space a unit of mass occupies.
