Assertion: Entropy of ice is less than water.
Reason: Ice has cage like structure.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
(b) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
(c) If the Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
(e) If the Assertion is incorrect but the Reason is correct.
(b) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
Explanation:
Entropy is defined as the extent of randomness in a system. When a substance is heated, its randomness and hence entropy increases. Thus entropy of ice is less than water because of lesser molecular motion in ice. It is also true that ice has an open cage like structure.
