A carnot engine takes 300 cal. of heat at 500 k and rejects 150 cal of heat to the sink. The temperature (in k) of sink is __________.

Two heat engines X and Y of same efficiency are connected in series in such a way that the sink of X works as source of Y. X receives heat at 900 K and rejects some heat to its sink at TK and in turn Y rejects heat to its sink at 400 K, then the temperature T is

A Carnot engine takes 300 calories of heat from a source at 500 K and rejects 150 calories of heat to the sink. The temperature of the sink is

A Carnot engine whose source is at 400 K takes 200 cal of heat and reject 150 cal to the sink . What is the temperature of the sink ?

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 :

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?
