Final Answer:
R-22 boils at minus (-41) degrees Fahrenheit.
Step-by-step explanation:
Refrigerant R-22, also known as chlorodifluoromethane, is commonly used in air conditioning and refrigeration systems. The temperature at which a refrigerant boils, also known as its boiling point, is a critical factor in its functionality. In this case, the statement indicates that R-22 boils at minus (-41) degrees Fahrenheit.
The boiling point of a substance is the temperature at which it transitions from a liquid to a vapor phase. In the context of refrigerants like R-22, this transition is crucial for the refrigeration cycle, where the refrigerant absorbs heat from the surroundings and undergoes phase changes to facilitate cooling. The specified boiling point of minus (-41) degrees Fahrenheit for R-22 indicates the temperature at which it undergoes this phase transition.
Understanding the boiling point of refrigerants is essential for designing and operating efficient refrigeration and air conditioning systems. The ability of R-22 to absorb heat and change from a liquid to a vapor at a relatively low temperature makes it suitable for various cooling applications. However, it's worth noting that R-22 has been phased out in many countries due to its environmental impact, and alternative refrigerants with lower global warming potential are now being used to comply with environmental regulations.
