Are entropy values for substance grater than or equal to zero?

1 Answer

Answer:

Unless there are exceptional circumstances, the entropy of any substance is #>0#.

Explanation:

The #"third law of thermodymamics"# states that #"the entropy of"# #"a perfect crystal at 0 K is ZERO.........."#

The law was formulated by Walther Nernst in 1906. Boltzmann later derived a statistical mechanical treatment that stated that #S=klnomega#, where #k="Boltzmann's constant"#, and #omega#, the number of microstates in the system. Since a perfect crystal is #"perfect"#, there is only the ONE microstate available for the system, and #ln(1)=0#.
