JEE Main & Advanced Physics Thermodynamical Processes Question Bank Topic Test - Thermodynamical Process (2021)

  • question_answer
    A system performs work \[\Delta W\] when an amount of heat is \[\Delta Q\] added to the system, the corresponding change in the internal energy is \[\Delta U\]. A unique function of the initial and final states (irrespective of the mode of change) is

    A) \[\Delta Q\]

    B) \[\Delta W\]

    C) \[\Delta U\] and \[\Delta Q\]

    D) \[\Delta U\]

    Correct Answer: D

    Solution :

    [d] Change in internal energy (DU) depends upon initial an find state of the function while DQ and DW are path dependent also.
