Vedclass · Answer

(A) The internal energy of a substance is the sum of all forms of energy present in the system,such as electronic,nuclear,vibrational,and rotational energies.Because it is impossible to determine the exact values of these constituent energies,the absolute value of the total internal energy of a substance cannot be determined.Therefore,the Assertion is correct,and the Reason provides the correct explanation for it.

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.
