Absolute Zero Temperature: Ideal Temperature: Coldest Possible Temperature
When German chemist WALTHER HERMAAN NERNST studied about the second law of thermodynamics, his mind was completely disturbed. He studied that the entropy of the universe keeps on increasing for all the processes occurring on its own. He thought that, what should be done so that the entropy of the universe will not increase and it will remain constant? Then he studied everything about entropy. After a lot of studying and research work, he discovered the " Third Law Of Thermodynamics ". In that, he used the concepts of " Absolute Zero Temperature " to limit the value of entropy to a pure perfect crystalline substance. He states the third law as " The entropy of a perfect crystal of a pure substance approaches zero as the temperature approaches zero ". Generally, entropy increases with increase in system temperature and decreases with decrease in system temperature. At Absolute Zero Temperature (0 Kelvin temperature), all modes of motion stop (no translati...
