A Carnot engine takes an amount of heat QH = 113 J from a high-temperature reservoir at temperature TH = 1170°C, and exhausts the remaining heat into a low-temperature reservoir at TL = 13.3°C. Find the amount of work that is obtained from this process

    First, convert temperatures to absolute units.
    TH = 1443 K
    TL = 286.5 K
    Carnot Efficiency =
    Wout/Qin = (Qin - Qout)/Qin
    = 1 - (Tc/Th) = 0.802

    Work out = (efficiency)*113 = 90.6 J
