Why is flammability considered a chemical property rather than a physical property?
Answer (2)
Because combustion is a chemical change. A chemical change is defined by one or more substances being changed into one or more new substances. This being said, since when something is set on fire it changes the substance, it is a chemical change.
Flammability is a chemical property because it describes how a substance reacts and changes during combustion, resulting in new substances. Unlike physical properties, which can be observed without altering the material's identity, chemical properties indicate a transformation in chemical composition. When substances burn, their chemical structure changes, demonstrating the definition of a chemical change.
