The efficiency of a Carnot heat engine

Heat engine rejects some heat to the sink. This heat

The efficiency of a Carnot engine is 1/2. If the sink temperature is reduced by 100^@ C , then engine efficiency becomes 2/3. Find the source temperature and sink temperature.

Efficiency of a Carnot heat engine may be given as

Assertion : Efficiency of a Carnot engine increase on reducing the temperature of sink. Reason : The efficiency of a Carnot engine is defined as ratio of net mechanical work done per cycle by the gas to the amount of heat energy absorbed per cycle from the source.

The efficiency of carnot's heat engine is 0.5 when the temperature of the source is T_(1) and that of sink is T_(2) .The efficiency of another crot's heat engine is also 0.5.the temperature of source and sink of the second engine are respecitvely

A carnot engine operates with source at 127^(@)C and sink at 27^(@)C . If the source supplies 40kJ of heat energy. The work done by the engine 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 :
