Which of the follow- ing can be true (1) P_(A)=P_(B),V_(A)neP_(B)V_(B) (2) P_(A)V_(B)=P_(B)V_(B) (3) P_(A)neP_(B),V_(A)=V_(B) (4) P_(A)/(V_(A))=P_(B)/V_(B)

For an ideal gas, an illustration of the different paths, A (B + C) and (D + E) from an intial state P_(1), V_(1), T_(1) to a final state P_(2), V_(2), T_(1) as shown in the given figure. Path (A) represents a reversible isothernal expanison from P_(1)V_(1) to P_(2)V_(2) . Path (B + C) represents a reversible adiabatic expansion (B) from P_(1), V_(1), T_(1) to P_(3), V_(2), T_(2) followed by reversible heating the gas at constant volume (C) from P_(3), V_(2), T_(2) to P_(2), V_(2) T_(1) to P_(1) , V_(2), T_(3) followed by reversible cooling at a constant volume V_(2) (E) from P_(1), V_(2), T_(3) to P_(2), V_(2), T_(1) What is Delta S for path (D + E) ?
