Which of the following temperatures has a specific volume liquid of 0.0238?

• A. -15
• B. -16
• C. -18
• D. -19

Answer: (B)

To determine the correct temperature associated with a specific volume of liquid at 0.0238, it's essential to reference the properties of refrigerants and their behaviors at different temperatures. The specific volume of a liquid is influenced by temperature, pressure, and the liquid's composition, and typically, as the temperature decreases, the specific volume of a liquid refrigerant also decreases. In this case, a specific volume of 0.0238 is indicative of conditions close to freezing points for common refrigerants, such as R-134a or R-22, which is consistent with a moderate subzero temperature. The temperature that correlates with this specific volume of 0.0238 indicates a balance between being cold enough to retain the density required without being too low where the liquid might condense further or freeze. Given the temperatures provided, -16 degrees is likely the one matching the specific volume of 0.0238. In the context of the choices presented, -15 and -19 degrees would either be too high or too low, leading to significantly different specific volumes. Understanding these principles allows operators to correlate temperature with specific volumes effectively, which is crucial for maintaining system efficiency and safety in industrial refrigeration settings.
