Thermodynamics

Thermodynamics is a branch of chemistry that deals with the flow of heat in any form of energy from any systen to surrounding of that system or from surrounding of any system into the system. Three laws are concerned with the study of thermodynamics. These are first law of thermodynamics, second law of thermodynamics and the third law of thermodynamics. The importance of thermodynamics is found in some of the important branch and theories of chemistry. Mostly in physical chemistry thermodynamics have a wide range of importance. Specially, Vant Hoff law of vapour pressure lowering can derived from thermodynamics. Thermodynamics also plays an important role in deriving of phase rule and distribution law. How far a chemical and physical change may happen that also can predict by the study of thermodynamics. Though thermodynamics plays most important role in chemistry, but it is not free of limitation. It is only effective in macroscopic system but not in microscopic system. Time factor is not the subject of consideration in thermodynamics.

Attractive force

The force acting among the objects that tends to closer together is attractive force. The opposite concept of attractive force is repulsive ...
