Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

As you know entropy in reversible process is constant so change in entropy would be zero.so 1 is correct. In an ideal thermodynamically reversible process, the energy from work performed by or on the system would be maximized, and that from heat would be zero. so 2 is also correct. and also we know more heat is converted into work in reversible process due to no loss.so 3 is also correct.

1. option 1st is correct as u discussed a lot in one previous question of urs.. so statement 1is correct .. 2. for reversible cyclic process, close integration of dQ/T=0 so dQ=0 while close integration of dQ/T<0 in irreversible case so dQ<0 therefore statement 2 is correct.. 3 and 4statement also correct as more heat converted into work and vice versa in case of reversible cyclic process
