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. [2009] ### Column-I ### Column-II| (A) The energy of the system is increased | (p) <i>System</i> : A capacitor, initially uncharged<br><i>Process</i> : 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) <i>System</i> : A gas in an adiabatic container fitted with an adiabatic piston<br><i>Process</i> : The gas is compressed by pushing the piston |
| (C) Internal energy of the system is converted into its mechanical energy | (r) <i>System</i> : A gas in a rigid container<br><i>Process</i> : The gas gets cooled due to colder atmosphere surrounding it |
| (D) Mass of the system is decreased | (s) <i>System</i> : A heavy nucleus, initially at rest<br><i>Process</i> : The nucleus fissions into two fragments of nearly equal masses and some neutrons are emitted<br>(t) <i>System</i> : A resistive wire loop<br><i>Process</i> : The loop is placed in a time varying magnetic field perpendicular to its plane |
