Question
The entropy of a pure crystalline substance at absolute zero is:Question 6Select one:a.always greater than zerob.zeroc.less than zerod.generally zero, but can be greater than zero in certain circumstances
Solution
The correct answer is b. zero. According to the third law of thermodynamics, the entropy of a pure crystalline substance at absolute zero is zero. This is because a perfect crystal exists in only one state, and therefore has no disorder.
