1.	Some statements are given with regard to entropy. The incorrect statement(s) are (A) The absolute entropy of substances cannot be determined (B) In standard state entropy of elements is always positive (C ) The entropy of universe always decreases (D) In a spontaneous process, for an isolated system the entropy of the system generally increases
Answer» A, B B,C A,C only C Solution :Absolute Entropy of SYSTEM can be CALCULATED from THIRD LAW of Thermodynamics. As per SECOND law of Thermodynamics Entropy of universetends to increases
