Two moles of a diatomic gas are carried through the cycle ABCDA shown in the PV diagram
Question:
Two moles of a diatomic gas are carried through the cycle ABCDA shown in the PV diagram in figure. The segment AB represents an isothermal expansion, the segment BC an adiabatic expansion. The pressure and temperature at A are 5 atm and 600 K. The volume at B is twice that at A. The pressure at D is 1atm.
(a) What is the pressure at B?
(b) What is the temperature at C?
(c) Find the work done by the gas in one cycle and the thermodynamic efficiency of thiscycle.

I believe everyone should try to be strong at logic and have good reading habit. Because If you possess these two skills, no matter what difficult situation is, you will definitely find a perfect solution out of it. While logical ability gives you to understand complex problems and concepts quite easily, reading habit gives you an open mind and holistic approach to see much bigger picture.
So guys, I always try to explain any concept keeping these two points in my mind. So that you will never forget any more importantly get bored.
Last but not the least, I am finance enthusiast. Big fan of Warren buffet for long term focus investing approach. On the same side derivatives is the segment I possess expertise.
