    Which of the two
    (i) Compressing a gas isothermally until its volume is reduced by half              
    (ii) Compressing the same gas adiabatically until its volume is reduced by half, require more work to be done?

    A)  (i)                                         

    B)  (ii)                                  

    C)  Both will require the same amount of work

    D)  It will depend upon the nature of the gas

    Correct Answer: B

    Solution :

    \[W=\mu R+{{\log }_{e}}\frac{{{v}_{2}}}{{{v}_{1}}}\] Isothermal process will require more work done.
