WHAT IS THE THIRD LAW OF THERMODYNAMIC ?

In this article we are going to discuss about the " Third Law Of Thermodynamics" its statement is given by a chemist Nernst walther in 1912 .

STATEMENT - " The Entropy of a perfect crystal at absolute zero temperature is zero "

 

[since its impossible to attain absolute zero temperature in finite number of operation's] .

 CONCLUSION -
Although its impossible to attain absolute zero temperature because some internal energy always remains in molecules meanwhile refer this law as limiting behavior for any object .

FOOTNOTES -

* Entropy - measure of how much , molecules can move disorderly

* Perfect crystal - perfect crystal has definite size and arrangement of its unit cell throughout 3 - dimension without any single defect . 

* Absolute temperature - "0 kelvin " or ( - 273.15 degree Celsius ) . it is a minimum temperature any object could have .
