For example, if we tear a piece of paper, it remains paper and its chemical composition doesn’t change.
Physical properties are independent of their chemical composition. Physical properties include those properties that can be easily measured and are observable. It can be any object’s colour, hardness, weight, malleability, length, mass, density, temperature and many more. Properties of matter refer to those traits that can be measured. Properties are the characteristics that enable us to differentiate between two materials. In gases, the molecules are very loosely arranged and they neither have a definite shape nor fixed volume. In liquids, the molecules are loosely packed and hence they do not have a definite shape but a fixed volume. 
If the molecules are tightly packed giving a substance fixed shape and volume, it is solid. The state of matter is determined by the molecules present in it. It exists primarily in three forms solid, liquid and gas. A matter is any substance that occupies space and has a mass and volume.
Keyterms: solid, liquid, gas, atoms, motion, Opaque, reactivity, flammability, corrosiveness, toxicity, acidity, explosivenessĪll physical structures are made up of Matter.
