Final answer:
Flammability is a physical property that indicates the ability of a substance to catch fire and sustain a flame. It is an important property to consider for safety purposes. Other properties related to flammability include flash point, autoignition temperature, and fire point.
Step-by-step explanation:
Flammability is a physical property that appears on an SDS (Safety Data Sheet) related to the ability of a substance to burn or support combustion. It is a measure of how easily a substance can catch fire and sustain a flame.
For example, gasoline has a high flammability because it can easily vaporize and ignite in the presence of a spark or flame.
Other physical properties related to flammability include flash point (the minimum temperature at which a substance can ignite), autoignition temperature (the temperature at which a substance can ignite without an external ignition source), and fire point (the temperature at which a substance can sustain a flame).
