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

Options

A. Internal energies at A and B are the same
B. Work done by the gas process AB is `P_(0)V_(0)` in 4
C. Pressure at C is `(P_(0))/4`
D. Temperature at C is `(T_(0))/4`

Answer

A, B

Explanation

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.
