Real Gases

A gas which obeys the ideal gas equation, PV =nRT under all conditions of temperature and pressure is called an ideal gas. There is no...

Viscosity

Some liquids like water, ether flow rapidly why some other liquids like glycerine ,castor oil flow quite slowly. This internal resistance to flow possessed by...

Surface Tension

Surface tension is a property of liquid which arises due to the fact that the molecules of the liquid at the surface are in different...

Vapour Pressure

In a liquid, the molecules are quite close together so that there are considerable forces of attraction between them and hence they are held together...

Deduction of Gas Laws From kinetic Theory

Boyle’s law At constant temperature, the average kinetic energy and hence the average speed of the molecules is constant.The number of molecules present in a...

Maxwell-Boltzmann Distribution

Maxwell-Boltzmann distribution of Molecular speed At a particular temperatures, different molecules of a gas possess different speeds. Due to continues collision among the molecules themselves...

Kinetic Molecular Theory Of Gas

Kinetic theory of gases Postulates or assumptions of kinetic theory of gases 1)Every gas is made up of a large number of extremely small particles...

Gas Laws

Boyle’s law The relationship between the volume and pressure of a gas was studied experimentally by Robert Boyle in 1662. He used mercury and a...

Characteristics Of Gases

Characteristics of gases 1)Gases have neither definite shape nor definite volume. They take up the shape and volume of the container. 2)They have lower density...

Intermolecular forces

A given substance can be made to exist in any one of the three states under different conditions of temperature and pressure. Water which is...
