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

  • question_answer
    The internal energy of the gas increases In

    A) Adiabatic expansion       

    B) Adiabatic compression

    C) Isothermal expansion      

    D) Isothermal compression

    Correct Answer: B

    Solution :

    [b] In adiabatic process DU = – DW. In compression DW is negative, so DU is positive i.e. internal energy increases.
