A Carnot enginer abosrbs an amount Q of heat from a reservoir at an absolute temperature T and rejects heat to a sink at a temperature of `T//3`. The amount of heat rejects is

Two Carnot engines A and B operate in series such hat engine A absorbs heat at T_(1) and rejects heat to a sink at temperature T. Engine B absorbs half of the heat rejected by Engine A and rejects heat to the sink at T_(3) . When workdone in both the cases is equal, to value of T is :

A Carnot engine absorbs 750 J of heat energy from a reservoir at 137^(@)C and rejects 500 J of heat during each cycle then the temperature of sink is

Two Carnot engines A and B are operated in series. The engine A receives heat from the source at temperature T_1 and rejects the heat to the sink at temperature T. The second engine B receives the heat at temperature T and rejects to its sink at temperature T_(2) . For what value of T the efficiencies of the two engines are equal?

Two carnot engines A and B are operated in series .Engine A receives heat from a reservoier at 600 K and rejectrs heat to a reservoir at temperatures T. Engine B receives heat rejected by engine A and in turn rejects it to a reservoir at 100 K .If the efficiencies of the two engines A and B are represented by eta_(A) and eta_(B) repectively then what is the value of (eta_(B))/(eta_(A)) ?

Heat engine rejects some heat to the sink. This heat
