Multiple Choice

A liquid with a flash point of 140 degrees F is classified as combustible.

Explanation:
Flash point determines whether a liquid is flammable or combustible: it’s the lowest temperature at which enough vapor forms to ignite in air. If the flash point is below 100°F, the liquid is considered flammable; if it’s at or above 100°F, it’s considered combustible. A flash point of 140°F is above the 100°F threshold, so the liquid is classified as combustible. Therefore the statement is true.
