Question 595: Thermodynamics & KTG

Question

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.

Accepted Answer

$$\left( {1 - {{324} \over {{T_H}}}} ight) = {{300 - 180} \over {300}}$$
$$1 - {2 \over 5} = {{324} \over {{T_H}}}$$
$${T_H} = {{324 	imes 5} \over 3} = 540$$
