Assertion: Absolute values of internal energy of substances cannot be determined.
Assertion: Absolute values of internal energy of substances cannot be determined.
Reason: It is impossible to determine exact values of constituent energies of the substances.
(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.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
Explanation:
Absolute values of internal energy of substance can not be determined because it is impossible to determine exact values of constituent energies of the substances.
