Question 628: Thermodynamics & KTG

Question

A Carnot engine operates between two reservoirs of temperatures 900 K and 300 K. The engine
performs 1200 J of work per cycle. The heat energy (in J) delivered by the engine to the low
temperature reservoir, in a cycle, is _______.

Accepted Answer

So $${{Q + 1200} \over Q} = {{900} \over {300}}$$
$$ \Rightarrow $$ Q + 1200 = 3Q
$$ \Rightarrow $$ Q = 600 J
