Question 661Deck Safety70% to pass
The volatility of a flammable liquid is indicated by its _______________.
AI Explanation
The correct answer is D) flash point.
The flash point of a flammable liquid is the temperature at which the liquid gives off enough vapors to form an ignitable mixture with air. The lower the flash point, the more volatile the liquid, meaning it can more easily ignite and burn. The flash point is the primary indicator of a liquid's volatility, as it directly measures the ease with which the liquid can be ignited.
The other answer choices are not directly related to a liquid's volatility. The conversion index and ignition temperature are not volatility measures, while the flammable range indicates the concentrations of vapor in air that can burn, but does not specify the ease of ignition.
