The efficiency of a Carnot engine working between temperatures $127^\circ\text{C}$ and $27^\circ\text{C}$ is}

A Carnot engine operates between a heat source at $T_1 = 600\text{ K}$ and a sink at $T_2 = 300\text{ K}$. If the engine absorbs $1000\text{ J}$ of heat from the source per cycle, the work done per cycle is:

A Carnot engine operating between temperatures \(600\,K\) and \(300\,K\), absorbs \(800\,J\) of heat from the source. The mechanical work done per cycle is

The temperature of the sink of a Carnot engine is \(250\;K\). In order to increase the efficiency of the Carnot engine from \(25\%\) to \(50\%\), the temperature of the source should be increased by

A Carnot engine is working between a source at constant temperature \(T_1\) and a sink at temperature \(T_2\). Its efficiency is \(\frac{1}{8}\). Upon decreasing the temperature of the sink by 50°C, the efficiency becomes \(\frac{1}{4}\). Find \(T_1\) and \(T_2\).

A Carnot engine operating between 430 K and 330 K does a work of 60 kJ. The amount of ice that can melt from its exhaust is (Latent heat of fusion of ice = 330 J g\(^{-1}\)).

A heat engine operates between a cold reservoir at temperature 300 K and a hot reservoir at temperature \(T_1\). It takes 200 J of heat from the hot reservoir and delivers 120 J of heat to the cold reservoir in a cycle. The minimum temperature \(T_1\) of the hot reservoir is:

A gas in a closed container undergoes the cycle ABCDA as shown in the figure. The net heat absorbed by the gas after it has completed 20 cycles is:

A Carnot engine operates between heat reservoirs differing in temperature by 80 °C. The efficiency of the Carnot engine is \(20\%\). The temperature of the cold reservoir is:
