At what pressure will refrigerant R-11 boil approximately at 14.7 psia?

To determine the boiling point of refrigerant R-11 at a pressure of 14.7 psia, it is essential to refer to the refrigerant's pressure-temperature relationship, which is typically found in refrigerant tables. At a pressure of 14.7 psia, R-11 has a boiling point of approximately 74.9 degrees Fahrenheit.

This temperature corresponds to the condition where the refrigerant transitions from a liquid to a vapor state, making it critical for understanding its application in low-pressure systems. The significance of knowing this boiling point lies in the safe and efficient operation of refrigeration and air conditioning systems that utilize R-11, allowing technicians to ensure optimal system performance and proper refrigerant management.

In this context, the other temperature choices do not align with the established boiling point of R-11 at 14.7 psia, highlighting the importance of having accurate data when working with refrigerants. Understanding temperature and pressure relationships is fundamental in the servicing and maintenance of refrigerant systems.
