JEE Main & Advanced Physics Thermodynamical Processes Question Bank Adiabatic Process

  • question_answer
    Two identical samples of a gas are allowed to expand (i) isothermally (ii) adiabatically. Work done is         [MNR 1998]

    A)            More in the isothermal process

    B)            More in the adiabatic process

    C)            Neither of them

    D)            Equal in both processes

    Correct Answer: A

    Solution :

                       In thermodynamic processes. Work done = Area covered by PV diagram with V-axis From graph it is clear that \[{{(\text{Area})}_{iso}}>{{(\text{Area})}_{adi}}\] Þ \[{{W}_{iso}}>{{W}_{adi}}\]
