pure substance properties
Introduction to properties of pure substance:
Let us discuss the properties of pure substance. A complete set of properties is unique for a given pure substance. Thus, if two samples of matter have identical sets of properties sets of properties, they are the samples of the same pure substance. Some of the important physical properties that can be used to recognize a pure substance are given below.

Properties of pure substances
There are seven properties used in the pure substance. That property is given below.
Density
Melting point
Boiling point
Refractive index
Electrical conductivity
Viscosity
Absorption spectrum
The first property is density. The density is determined by the mass per unit volume. It is usually expressed in grams per cubic centimeter (g/cc).
The second property is melting point. The melting point is temperature at which a solid is altered into a liquid.
The third property is boiling point. It is the temperature at which a liquid is rapidly converted into its vapour at one atmospheric pressure.
The fourth property is refractive index. The refractive index is related to the speed at which light travels in the given sample of matter and can be measured accurately in terms of the angles at which the light enters and leaves the substance.
The fifth property is electrical conductivity. It is a measure of the ease with which an electric current can exceed from side to side the substance. Copper is an excellent conductor of electricity, while glass is an insulator or poor conductor of electricity.

Other Properties of pure substance
The sixth property is viscosity. The viscosity is a measure of the case with which a liquid or a gas can flow. For example, water will flow much more readily than mobil oil.
The last type is absorption spectrum. The absorption spectrum of a substance is a catalogue of the wave lengths which the substance absorbs from visible, infrared and ultraviolet light.
