At 101.3 kPa, what is the boiling point of ammonia?

• A. 0 C
• B. -33.3 C
• C. -10 C
• D. -25 C

Answer: (B)

The boiling point of ammonia at a pressure of 101.3 kPa—or approximately 1 atmosphere—is -33.3 degrees Celsius. This temperature is significant in understanding ammonia as a refrigerant, especially since its widely applicable properties in refrigeration cycles depend heavily on its boiling point characteristics. At this pressure, ammonia transitions from a liquid to a gas, and this boiling point is lower than that of water, illustrating the effectiveness of ammonia as a refrigerant, particularly in low-temperature applications. This low boiling point ensures that ammonia can absorb heat effectively and provide the necessary cooling effect, which is a crucial aspect of refrigeration systems.
