Recreational Vehicle (RV) Technician Practice Test

What is the boiling temperature of propane at sea level?

1. -32 degrees Fahrenheit

2. -44 degrees Fahrenheit

3. 0 degrees Fahrenheit

4. 32 degrees Fahrenheit

The correct answer is: -44 degrees Fahrenheit

The boiling temperature of propane at sea level is approximately -44 degrees Fahrenheit. This means that at temperatures above this point, propane exists as a gas, and below this temperature, it can be found in a liquid state. Understanding the boiling point is crucial for RV technicians, as propane is commonly used as a fuel source for various appliances in recreational vehicles. Its properties can significantly impact the performance and safety of these systems. The other options represent temperatures that do not correlate with the known boiling point of propane under standard atmospheric conditions. For example, -32 degrees Fahrenheit and 0 degrees Fahrenheit are too high for propane to maintain its liquid state, while 32 degrees Fahrenheit, the freezing point of water, is also much higher than the boiling point of propane. This makes it essential for technicians to have accurate information to ensure proper handling and usage of propane in RV applications.
