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 .,

MARKS App · Accepted Answer

Using the relation, Q 2 Q 1 = T 2 T 1 Or 180 300 = 324 T 1 ⇒ T 1 = 324 × 300 180 = 540 K
