Total: 57

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.
