Question: 1 / 400

What does the volatility of gasoline refer to?

ability to burn

tendency to vaporize

The volatility of gasoline refers to its tendency to vaporize. This property is crucial because gasoline needs to convert from a liquid to a vapor to mix with air and ignite in the combustion chamber of an engine. A highly volatile gasoline can vaporize easily at relatively low temperatures, facilitating efficient combustion and engine performance. Factors like temperature, pressure, and the composition of the gasoline itself can affect volatility; thus, it is essential for optimal starting, running, and overall efficiency of the engine. Understanding the volatility of gasoline aids in selecting appropriate fuels for varying environmental conditions and engine designs.
