Properties of matter and their measurements

The property of matter can be classified into categories physical properties and chemical properties.

1. Physical properties - physical properties are those properties which can be measured or observed without changing the identity or the composition of a substance. Some examples of physical properties are colour, smell, melting point ,boiling point ,density etc.                               
2. Chemical properties- the measurement of chemical properties requires a chemical change to occur. For example chemical properties are characteristic reactions of different substances, these include acidity or basicity, combustibility etc.

Many Properties of Matter such as length, area, volume are quantitative in nature full stop any quantitative observation on measurement is represented by a number followed by units in which it is measured. For example length of a room can be represented as 6 metre, here 6 is the number and M denotes metre the unit in which the length is measured.

Two different system of measurement that is the English system and the metric system working used in different parts of the world. The metric system which originated in France in late 18th century, was more convenient as it was based on the decimal system. The need of a common Standard System was being filled by the scientific community. Such a System was established in 1960.
