Column II gives certain systems undergoing a process. Column I suggests changes in some of the parameters related to the system. Match the statements in Column I to the appropriate process(es) from Column II:

Column I Column II
(A) The energy of the system is increased. (P) System : A capacitor, initially uncharged.
Process : It is connected to a battery.
(B) Mechanical energy is provided to the system, which is converted into energy of random motion of its parts. (Q) System : A gas in an adiabatic container filled with an adiabatic piston.
Process : The gas is compressed by pushing the piston.
(C) Internal energy of the system is converted into its mechanical energy. (R) System : A gas in a rigid container.
Process : The gas gets cooled due to colder atmosphere surrounding it.
(D) Mass of the system is decreased. (S) System : A heavy nucleus, initially at rest.
Process : The nucleus fissions into two fragments of nearly equal masses and some neutrons are emitted.
(T) System : A resistive wire loop.
Process : The loop is placed in a time varying magnetic field perpendicular to its plane.
