A perfect gas goes from state $\mathrm{A}$ to state $\mathrm{B}$ by absorbing $8\times {10}^5 \mathrm{J}$ of heat and doing $6.5\times {10}^5 \mathrm{J}$ of external work. It is now transferred between the same two states in another process in which it absorbs ${10}^5$ J of heat. In the second process,
