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

  • question_answer
    Assertion             :       We can not change the temperature of a body without giving (or taking) heat to (or from) it. Reason                 :       According to principle of conservation of energy, total energy of a system should remains conserved.

    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: D

    Solution :

                We can change the temperature of a body without giving (or taking) heat to (or from) it. For example in an adiabatic compression temperature rises and in an adiabatic expansion temperature false, although no heat is given or taken from the system in the respective changes.
