A heat engine operates with the cold reservoir at temperature 324 K. The minimum temperature of the hot reservoir, if the heat engine takes 300 J heat from the hot reservoir and delivers 180 J heat to the cold reservoir per cycle, is ____________ K.
Answer (integer)
540
Solution
<p>$\left( {1 - {{324} \over {{T_H}}}} \right) = {{300 - 180} \over {300}}$</p>
<p>$1 - {2 \over 5} = {{324} \over {{T_H}}}$</p>
<p>${T_H} = {{324 \times 5} \over 3} = 540$</p>
