1.	In the graph shown below A-B, B-C , C-D are parts of the carnot cycle operating on an ideal gas.Consider only the path from State 1 to State 2 . W denotes the work in the path. Equations and plots in the table have standard notations gamma is the ratio of heat capacities at constant pressure and constant volume. The moles of the gas is 'n'. For which of the following options dQ_(rev_(sys))/T=0 and dQ_(rev(sys))/T=0 it taken irreversibly
Answer» (I)(iv)(Q) (IV)(i)(P) (II)(iii)(R) None of these Solution :For adiabatic reversible `dQ_("reversible")=0` and if taken IRREVERSIBLE `dQ_("reversible")=0` Hence CORRECT OPTION is (I)(iv)(Q)
