JEE Main & Advanced Physics Thermodynamical Processes Question Bank Adiabatic Process

  • question_answer
    During an adiabatic expansion of 2 moles of a gas, the change in internal energy was found ?50J. The work done during the process is                                                          [Pb. PET 1996]

    A)            Zero                                         

    B)             100J

    C)            ? 50J                                        

    D)             50J

    Correct Answer: D

    Solution :

                       For adiabatic forces \[\Delta W=-\Delta U\]      \[(\because \Delta Q=0)\]            Þ \[\Delta W=-(-50)=+50J\]
