What is the flashpoint of gasoline?

Very high
Moderate
Very low
Non-flammable

The correct answer is: Very low

The flashpoint of a substance is the lowest temperature at which it can vaporize to form an ignitable mixture in air. Gasoline has a flashpoint that is classified as very low, typically ranging from about -45 degrees Fahrenheit (-43 degrees Celsius) to around -40 degrees Fahrenheit (-40 degrees Celsius). This means gasoline can easily ignite at or above these temperatures, which is a significant characteristic highlighting its flammability and the need for careful handling and storage. Understanding the flashpoint is crucial for safety in environments where gasoline is used or stored, as it indicates the risk of fire and dictates specific safety regulations and practices. For example, because of gasoline's low flashpoint, regulations require that it be stored in approved containers and kept away from sources of ignition. In contrast, other options indicate different flashpoint characteristics: "very high" implies a material that would be much less prone to ignite easily, "moderate" suggests a flashpoint that is higher than gasoline but not excessively so, and "non-flammable" refers to substances that do not ignite at any temperature under typical conditions. Such distinctions are vital for understanding the safe handling of various flammable materials.
