    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

    3. The attempt at a solution

    Your result for the work done in the cycle looks correct.

    In the next line you have calculated some heat Q. Please explain what heat this represents and how you got this result.
