What two physical characteristics of a liquid are principally used to determine its flammability classification?
A)flashpoint and boiling point
B)flashpoint and firepoint
C)boiling point and firepoint
D)volatility and boiling point

Question

Quizplus · Accepted Answer

Flashpoint is the lowest temperature at which a liquid can form an ignitable mixture with air near the surface of the liquid. Boiling point is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. These two properties are used to determine the flammability classification of a liquid because they indicate the relative ease with which a liquid can be ignited and the temperature range over which it can burn.
