Question: What is the evaporation temperature of R-134a at 0 psig?

a. -21°F

b. -15°F

c. -5°F

d. -1°F”

The correct answer is: b. -15°F

The evaporation (or boiling) temperature of R-134a at 0 psig is approximately -15°F (-26°C).

This is the temperature at which R-134a refrigerant will change from a liquid to a vapor at atmospheric pressure (0 psig), making it suitable for refrigeration and air conditioning systems where lower temperatures are needed.
