Question
State the third law of thermodynamics.
Short Note
Solution
The third law of thermodynamics states that the entropy of pure crystalline substance at absolute zero is zero. Otherwise, it can be stated as it is impossible to lower the temperature of an object to absolute zero in a finite number of steps. Mathematically,
`lim_("T"->0)` S = 0 for a perfectly ordered crystalline state.
