Which of the following describes a volatile flammable liquid?

A volatile flammable liquid is characterized by having a flash point below a certain temperature, which signifies the lowest temperature at which the liquid can produce enough vapor to ignite in air. Specifically, a flash point below 38°C (100°F) indicates that the liquid can easily release vapors that can ignite at relatively low temperatures, posing significant fire and explosion hazards. Therefore, any liquid that has a flash point below this temperature is considered volatile because it can readily evaporate into flammable vapors under normal atmospheric conditions, leading to a risk of ignition.

This understanding is crucial for safety in various applications, especially in storage, handling, and usage where the presence of such liquids can lead to dangerous situations if proper precautions are not taken. The other descriptions do not accurately reflect the properties of volatile flammable liquids. For instance, a high flash point would not classify as volatile in terms of flammability, nor would a liquid that cannot ignite or is non-flammable fit the definition since they do not present fire hazards.
