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

A carnot engine absorbs heat from a reservoir maintained at temperature 1000K. The engine rejects heat to a reservoir whose temperature is T. If the magnitude of a absorbed heat is 400J and work performed is 300J, then the value of T is

A carnot engine absorbs 40 cal heat from source having temperature 320 K and rejects 30 cal heat to sink . The temperature of the is

A Carnot heat engine absorbs 600J of heat from source of temperature 800K and rejects 300J of heat to the sink. Calculate efficiency and 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 :

A Carnot engine absorbs 1000 J of heat from a reservoir at 127^@C and rejects 600 J of heat during each cycle.Calculatethe temperature of the sink

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
