An ideal diatomic gas is taken along the cyclic process ABCA. Heat given by the system in the process A to B 50 J and work done on the gas is 50 J. In the process B to C volume doubles at constant pressure. The process CA is isochoric.
The relation between temperature TA and TB is
(A) TA > TB
(B) TA < TB
(C) TA = TB
(D) data indequate
