State the third law of thermodynamics.

Text Solution

Verified by Experts

Third law of thermodynamics : The entropy of a pure and perfectly crystaline substance is zero at the absolute zero of a temperature `(-273^@C)`
`S_("lim T" to 0)=0`
This law imposes a limination on the value of entropy.
`S_T=underset(0)overset(T)int C_P/T. dT`
