An ideal gas is made to undergo a cycle depicted by the \((P-V)\) diagram alongside. If the curved line from \(A\) to \(B\) is adiabatic, then:
                    

1. the efficiency of this cycle is given by unity as no heat is released during the cycle.
2. heat is absorbed in the upper part of the straight-line path and released in the lower.
3. if \(T_1\) and \(T_2\) are the maximum and minimum temperatures reached during the cycle, then the efficiency is given by, \(1-\frac{T_2}{T_1}.\)
4. the cycle can only be carried out in the reverse direction as shown in the figure.
