What phase of fuel is acetone categorized as?

Acetone is categorized as a liquid phase fuel under standard conditions. It has a boiling point of 56.05 degrees Celsius, which means that at room temperature and normal atmospheric pressure, acetone exists as a clear, volatile liquid. This property allows acetone to easily evaporate into vapor, contributing to its flammability when mixed with air. While acetone can generate vapor, which is a gaseous phase, its primary state in typical handling and storage situations is liquid. Understanding the phase of fuels is crucial for assessing their behavior in fire hazards, as different phases have different ignition and combustion characteristics.
