The initial boiling point of commercial propane at a pressure of 14.7 psia (atmospheric pressure) is -44 degrees Fahrenheit. This figure is critical because it signifies that propane is a gas at room temperature and pressure, but it will transition to a liquid phase at lower temperatures. Understanding the boiling point is essential for handling propane safely and effectively, particularly in applications where it must remain in a gaseous state for optimal performance.

In propane's case, knowing it boils at -44 degrees Fahrenheit helps users grasp why it can remain in a liquid state under pressure in tanks but will vaporize at temperatures above this boiling point when the pressure is released. The temperature provides a benchmark for storage and handling practices, ensuring that the propane remains usable in its desired form for various applications, including heating, cooking, and fueling.

Additional options listed, such as -32 degrees Fahrenheit, 0 degrees Fahrenheit, and 32 degrees Fahrenheit, are not applicable as boiling points for commercial propane at atmospheric pressure. Each of these temperatures would imply a different state change for propane under those specific conditions, leading to potential misunderstandings about its handling and use.
