    1. The problem statement, all variables and given/known data

    An ideal gas adiabatic coefficient γ is submitted to the ABCA cycle of fig, where AB is a line segment..
    a) Calculate the income.
    b) Show that it is smaller than the yield of a Carnot cycle operating between the same temperature extremes.

    this is my attempt.

    2. Relevant equations

    P=nRT/V
