    \[\text{ }\!\!\Delta\!\!\text{ U}\]is equal to                            JEE Main Solved Paper-2017

    A)  Isochoric work

    B)  Isobaric work

    C)  Adiabatic work                

    D)  Isothermal work

    Correct Answer: C

    Solution :

     From 1st law                 \[\Delta U=q+w\] For adiabatic process: q = 0 \[\therefore \]  \[\Delta U=w\] \[\therefore \]Work involve in adiabatic process is at the expense of change in internal energy of the system.
