At what temperature does propane start to vaporize?

Propane begins to vaporize at a temperature of approximately -42°F (-41°C). This property is crucial to understand because it indicates the point at which liquid propane changes into a gaseous state under atmospheric pressure.

Vaporization is essential for the functioning of propane systems, as propane needs to be in its vapor state to be transported and used effectively. Knowing this temperature helps technicians ensure that propane is stored and handled properly, especially in colder climates where the risk of it remaining in liquid form can affect performance.

The other options suggest temperatures where propane would remain in a liquid state or not be able to vaporize effectively, which would impede its use in various applications. Understanding the correct vaporization temperature ensures that technicians can make informed decisions regarding propane handling and usage.
