1.	Which of the following permits the calculation of absolute values of entropy of a pure substance from thermal data alone?A. Second law of thermodynamicsB. Third law of thermodynamicsC. First law of thermodynamicsD. Zeroth of thermodynamics
Answer» Correct Answer - B For a pure substance, this can be done by summing `q_(rev)` increments from `0 K` to `298 K`. Along with this information, we use the fact that the entropy of any pure, perfect crystalline substance approaches zero as the temperature approaches absolute zero.
