MCQ
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

Answer

Correct option: A.
$A-p, q, t \ \ B-q \ \ C-s \ \ D-s$
a
$(P) \rightarrow(A)$ : electric energy stored.

$(Q) \rightarrow(A B)$ energy supplied, increasing internal energy.

$(R) \rightarrow$ (none) energy reduces, heat flows out, internal energy drops.

$(S) \rightarrow(A C D)$ Mass to energy conversion

$( T ) \rightarrow( A )$ Current flows leading to heat generation
