GENERAL KNOWLEDGE

Detailed explanation-1: -Flammability is the ability of matter to burn. When matter burns, it combines with oxygen and changes to different substances. Wood is an example of flammable matter, as seen in Figurebelow. When wood burns, it changes to ashes, carbon dioxide, water vapor, and other gases.

Detailed explanation-2: -Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust.

Detailed explanation-3: -Flammability is a chemical property, like corrosion resistance. The physical properties of a material, such as its hardness, density, melting point and thermal conductivity, don’t require the use of force or chemical alteration to measure or observe. If a material melts, its phase changes, but not its identity.

Detailed explanation-4: -The change of one type of matter into another type (or the inability to change) is a chemical property. Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
