Every substance has unique or characteristic or uniqueproperties. These all types ofproperties can be classified into two categories or two groups — physicalproperties, such as colour, odour, melting point, boiling point, density, etc., and chemical properties, like composition, combustibility, reactivity with acids and bases, etc.
Physical properties can be measured or observed without changing the identity or the composition of the substance. The measurement or observation of chemical properties requires a chemical change or the change when chemicals react to occur. Measurement of physical properties does not require occurrence of a chemical change.
Quantitative measurement is required for scientific investigation. Many types of matter or any substance around us, such as length, area, volume, etc., are quantitative in nature. Any quantitative observation or measurement is represented by a number followed by units in which the object is measured. For example, length of a room can be represented as 6 m; here, 6 is the number and m denotes metre, the unit in which the length is measured.
