At what temperature does the specific volume measure 0.0679?

To determine the specific volume of a refrigerant at different temperatures, it's essential to understand the properties of the refrigerant being analyzed, which is typically based on tables or thermodynamic data. The specific volume is a crucial property in refrigeration cycles, as it represents the volume occupied by a unit mass of the refrigerant.

In this context, if the specific volume measures 0.0679 at a temperature of -20 degrees, it indicates that, at that temperature, the refrigerant has reached a certain pressure and density where the interactions of the gas molecules allow for that specific volume to be recorded. This value is indicative of the refrigerant being in a specific state, likely close to its saturation point and very relevant to accurate calculations for cooling efficiency.

Understanding this property and reading from refrigeration tables allows you to pinpoint the exact temperature where a certain specific volume occurs. The chosen answer aligns with these principles, confirming that at -20 degrees, the specific volume indeed measures 0.0679.
