Final answer:
Flammability is a chemical property of matter, involving a substance's capacity to burn, while mass, volume, and density are physical properties.
Step-by-step explanation:
Among the options provided, flammability is a chemical property of matter. Chemical properties describe how matter changes form in the presence of other matter or under certain conditions. Flammability is the ability of a substance to burn or ignite, causing fire or combustion.
This property is a measure of how a substance reacts with oxygen to release energy in the form of light and heat. On the other hand, mass, volume, and density are physical properties, which can be measured or observed without changing the chemical composition of a substance.
