JEE Advanced2009PhysicsWork, Power and EnergyActual
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.
Options
- A(A) q,t, (B) r, (C) t, (D) r
- B(A) p,q,s,t, (B) q, (C) s, (D) s
- C(A) p,s, (B) r, (C) s, (D) r
- D(A) p,q,s,t, (B) q, (C) t, (D) s
Correct answer
B. (A) p,q,s,t, (B) q, (C) s, (D) s
Step-by-step solution
A. The energy of the system is increased → p, q, s, t (Battery charging capacitor, gas compressed adiabatically, nucleus fission, induced current in loop) B. Mechanical energy → random motion → q (Gas compressed by piston → work converted to internal energy) C. Internal energy → mechanical energy → t (Induced current in resistive loop converts electrical/internal to mechanical form) D. Mass decreases → s (Nuclear fission → mass defect) ✅ Correct Answer: (2) (A) p,q,s,t ; (B) q ; (C) t ; (D) s
