JEE Main & Advanced Physics Thermodynamical Processes Question Bank Assertion and Reason

  • question_answer
    Assertion             :       The internal energy of an isothermal process does not change. Reason                 :       The internal energy of a system depends only on pressure of the system.

    A)             If both assertion and reason are true and the reason is the correct explanation of the assertion.

    B)             If both assertion and reason are true but reason is not the correct explanation of the assertion.

    C)             If assertion is true but reason is false.

    D)             If the assertion and reason both are false.

    E)             If assertion is false but reason is true.

    Correct Answer: C

    Solution :

                The internal energy of system depends only on its temperature. In isothermal process temperature does not change, therefore, internal energy of the system remains the same.
