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 fitted 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.
