Column II gives certain systems undergoing a process. Column I suggests changes in parameters related to the system. Match the statements in Column I to the appropriate process(es) in Column II.| Column I | Column II |
|---|---|
| (a) The energy of the system is increased | (p) System: an initially uncharged capacitor; 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 is cooled by the colder surrounding atmosphere |
| (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 |
