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.
