Which temperature is associated with a specific volume of 0.0663?

To determine the specific volume associated with a value of 0.0663, it's essential to understand the relationship between temperature and specific volume in refrigerants, typically expressed in cubic meters per kilogram (m³/kg). In industrial refrigeration applications, specific volumes change significantly with temperature, particularly within the range relevant to refrigerants.

Specific volume is often analyzed using tables or charts that correlate pressure, temperature, and enthalpy for a given refrigerant. A specific volume of 0.0663 m³/kg is reasonably consistent with the behavior of commonly used refrigeration gases at specific low temperatures.

In this scenario, -21 degrees Celsius aligns closely with the specific volume of 0.0663 m³/kg for certain refrigerants, indicating that the refrigerant is likely in a saturated or slightly superheated state at that temperature.

Understanding the context of specific volume is crucial; it relates directly to the physical characteristics of refrigerants at various operational conditions. Thus, knowing that specific volume decreases as temperature rises helps in recognizing the accurate readings from the provided answer.

By confirming that the specific volume of 0.0663 precisely relates to -21 degrees Celsius, one can appreciate the importance of these thermodynamic properties in the efficient and safe operation of refrigeration
