32 A Carnot engine is set up to produce a certain work W
per cycle. In each cycle, energy in the form of heat QH is
transferred to the working substance of the engine from
the higher-temperature thermal reservoir, which is at an adjustable
temperature T. The lower-temperature thermal reservoir is main-
tained at temperature T = 250 K. Figure 20-28 gives QH for a
range of TH. The scale of the vertical axis is set by QH. = 6.0 kJ. If
TH is set at 550 K, what is Qu?
