Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Heat is extracted from the source means heat is given to the system (or gas) or Q is positive. This is positive only along the path ABC points considered at the corner of the diagram.

see this attachment... if you have any doubt .. tell me
Yes I understood. thanks. I hv another doubt. what is the role of heat in AD & CD ?
We have to find the heat extracted from the source. Now heat extracted from the source will be in AB and BC path. AB path is a constant volume heat addition process and BC is a constant pressure expansion process. CA is a constant volume heat rejection process. AD is a constant pressure contraction process. That is why we only take AB and BC for heat extraction.
