View SolutionIn the Carnot engine,when heat is taken from the source,the temperature of the source
$A$ Carnot engine operates with a source at $227^{\circ}C$ and a sink at $27^{\circ}C$. If the source supplies $50 \ kJ$ of heat energy,the work done by the engine is (in $kJ$)
In a Carnot engine,if the temperatures of the source and the sink are decreased by $100 \ K$ each,then the efficiency of the engine:
