Question

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 (Take system as initially present things which are changing due to different activity done on them) Column I Column II

A	The energy of the system is increased	P	A capacitor is initially uncharged and 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	A gas is compressed by pushing the adiabatic piston fitted to an adiabatic container.
C	Internal energy of the system is converted into its mechanical energy	R	A gas in a rigid container is cooled due to surrounding colder atmosphere
D	Mass of the system is decreased	S	A heavy nucleus initially at rest fissions into two fragments of equal masses and some nearly nutrons are emitted
		T	A resistive wire loop is placed in a time varying magnetic field perpendicular to its plane

• A. A - (P,Q,R,S) ; B - (PQ) , C - (PS) ; D - (S)
• B. A - (P,Q,R,T) ; B - (Q) , C - (PS) ; D - (S)
• C. A - (P,,R,S) ; B - (PQ) , C - (PR) ; D - (S)
• D. A - (P,Q,S,T) ; B - (Q) , C - (S) ; D - (S)

Answer 1

The correct option is D A - (P,Q,S,T) ; B - (Q) , C - (S) ; D - (S)

$\left(P\right)\to \left(A\right):$ electric energy stored.
(Q) $\to \left(AB\right)$ energy supplied, increasing internal energy.
(R) $\to$ (none) energy reduces, heat flows out, internal energy drops.
(S) $\to \left(ACD\right)$ Mass to energy conversion
(T) $\to \left(A\right)$ Current flows leading to heat generation
$\therefore \left(A\right)\to \left(PQST\right),\left(B\right)\to \left(Q\right),\left(C\right)\to \left(S\right),\left(D\right)\to \left(S\right)$
