One mole of an ideal gas in initial state A undergoes a cyclic process

1.	One mole of an ideal gas in initial state A undergoes a cyclic process ABCA, as shown in the figure. Its pressure at A is `P_0`. Choose the correct option (s) from the following A. Internal energies at A and B are the sameB. Work done by the gas process AB is `P_(0)V_(0)` in 4C. Pressure at C is `(P_(0))/4`D. Temperature at C is `(T_(0))/4`
Answer» Correct Answer - A::B Process AB is isothermal process, Therfore, internal energies at A and B are the same. Work done by AB `W= RT_(0) "log"_(e)(4V_(0))/(V_(0))= P_(0)V_(0)"log"_(e)4` Since the coordinates of C are not given, hence we cannot predict the pressure and temperature at C.
