LAWS OF THERMODYNAMICS BASIC AND TUTORIALS


Thermodynamics studies the transformation of energy from one form to another and the interaction of energy with matter. It is a protracted and deductive science based on four strict laws. These laws bear the titles:

 “The Zeroth Law of Thermodynamics”, “The First Law of Thermodynamics”, “The Second Law of Thermodynamics”, and “The Third Law of Thermodynamics”.

 Laws are statements in agreement with all human experience and are always assumed to be true. Laws can not be proved; their validity rests upon the fact that neither the laws nor any of their consequences have ever been contradicted by experience.

Thermodynamics is a science built and based on these four basic laws. Among the four basic laws, The First Law of Thermodynamics and The Second Law of Thermodynamics are the two most useful to applied thermodynamics.

Zeroth law: Two systems which are each in thermal equilibrium with a third system are in thermal equilibrium with each other.

First law: Energy can neither be created nor destroyed.

Second law: Heat cannot flow spontaneously from a cold body to a hot body.

Third law: The entropy of all pure substances in thermodynamic equilibrium approaches zero as the temperature of the substance approaches absolute zero.
