A Carnot heat engine operates with an efficiency of 50%. If during each cycle it rejects 150 cal to a reserviour of heat at `30^circC` then what is the temperature of the other reservoir.

A Carnot heat engine operates with an efficiency of 50%. If during each cycle it rejects 150 cal to a reserviour of heat at 30^circC then how much work does it carry out per cycle?

A Carnot engine has an efficiency of 15.0%. It operates between constant temperature reservoirs differing in temperature by 55.0°C What is the temperature of the lower-temperature reservoir?

A Carnot engine, whose temperature of the source is 400K receives 200 calories of heat at this temperature and rejects 150 calaroies of heat to the sink. What is the temperature of the sink? Also, calculate the efficiency of the engine

A Carnot engine has efficiency 25%. It operates between reservoirs of constant temperatuers with temperature difference of 80^@C . What is the temperature of the low -temperature reservoir ?

In Carnot engine, efficiency is 40% at hot reservoir temperature T. For efficiency 50% , what will be the temperature of hot reservoir?

A Carnot engine whose low-temperature reservoir is at 350 K has efficiency of 50%. It is desired to increase this to 60%. It the temperature of the low-temperature reservoir remains constant, then the temperature reservoir remains constant, then the temperature of the high-temperature reservoir must be increased by how many degrees?

An ideal Carnot heat engine with an efficiency of 30% . It absorbs heat from a hot reservoir at 727^(@)C . The temperature of the cold reservoir is
