The specific volume of a liquid is defined as the volume occupied by a unit mass of the liquid and is typically expressed in cubic meters per kilogram (m³/kg). At temperatures around -22 degrees, evaluating the specific volume of a refrigerant or any liquid typically involves considering its physical properties, particularly its density.

For most common refrigerants at low temperatures like -22 degrees, the specific volume tends to be relatively consistent because liquids do not compress as much as gases. The specific volume reflects how much space a unit mass of liquid occupies, and at -22 degrees, the value that is closest to accepted data for a standard refrigerant is 0.0236 m³/kg. This value aligns with the expected behavior of refrigerants under these conditions, providing a practical reference for calculations in refrigeration systems.

The other options present values that slightly differ from the known properties of liquid refrigerants at that temperature, which makes them less accurate. When determining the specific volume, referencing reliable tables or thermodynamic properties of the specific fluid in question is crucial in practical applications, ensuring accurate readings for system calculations.
