Answer» Correct Answer - A-q ; B-p,r,s,t ; C-p,s ; D-r,t (A)`III^(rd)` law states `underset(Tto0)(Lim)Sto0` for perfect solid. (B)In reversible cyclic process the every net energy change is zero (i.e. `DeltaH_("sys")=0,DeltaU_("surr")=0` and net heat exchange =0) and `DeltaS_("surr")=0` (C ) In irreversible cyclic process `DeltaS_("sys")=0` but `DeltaS_("surrounding")gt0` by `II^(nd)` law and all state function are zero. (D)In adiabatic process net heat change is zero so `DeltaS_("surrounding")=0` |
