    Question

    Statement I: Glass is not considered as a true compound.

    Statement II: Glass does not have a definite melting point. Codes:
    A Both the statements are true and Statement II is the correct explanation of Statement I. Correct Answer Incorrect Answer
    B Both the statements are true but Statement II is not the correct explanation of Statement I. Correct Answer Incorrect Answer
    C Statement I is true, but Statement II is false. Correct Answer Incorrect Answer
    D Statement I is false, but Statement II is true. Correct Answer Incorrect Answer

    Solution

    • Glass is an amorphous solid, which means it lacks a long-range ordered structure. Hence, it is not a true compound but a mixture of substances like silica, soda, and lime.
    • Glass does not have a sharp melting point but softens over a range of temperatures because of its amorphous nature. Thus, both statements are true, and Statement II correctly explains Statement I.
