    Question

    Consider the following statements:   Assertion

    (A): During the winter season, a glass breaks when hot water it poured into it. Reason (R): The exterior surface of the glass material undergoes expansion when it comes in contact with the hot water.
    A Both (A) and (R) are true, but (R) is not the correct explanation for (A). Correct Answer Incorrect Answer
    B Both (A) and (R) are true and (R) correctly explains (A). Correct Answer Incorrect Answer
    C (A) is true, but (R) is false. Correct Answer Incorrect Answer
    D (A) is false, but (R) is true. Correct Answer Incorrect Answer

    Solution

    When during the winter season, hot water is poured in the glass, its inner surface undergoes expansion while the exterior surface which is in contact with cold atmosphere does not expand. This opposite interaction causes the glass surface to break. Thus, (A) is true, but (R) is false. Hence, the correct answer is (C).
