Carnot Engine

What is the sequence of expansion in the process of Carnot cycle?

Even Carnot engine cannot give $100\%$ efficiency because we cannot

The work done by the gas of thermal expansion in the Carnot cycle is

The efficiency of all reversible heat engines operating between the same heat reservoirs is :

The correct sequence of the processes taking place in a carnot cycle is

 A cyclic heat engine does 50kJ of work per cycle. If efficiency of engine is 75%, the heat rejected per cycle will be

A Carnot engine absorbs $750 \mathrm{J}$ of heat energy from a reservoir at $137 \mathrm{℃}$ and rejects $500 \mathrm{J}$ of heat during each cycle, then the temperature of sink is

Air in a cylinder is suddenly compressed by a piston which is then maintained at the same position. As the time passes, pressure of the gas,

A Carnot's cycle operating between ${\mathrm{T}}_1=600\mathrm{ }\mathrm{K}\mathrm{ }$ and ${\mathrm{T}}_2=300\mathrm{ }\mathrm{K}$ produces $1.5 \mathrm{k}\mathrm{J}$ of mechanical work per cycle. The heat transferred to the engine by the reservoir is:

A Carnot engine absorbs $750 \mathrm{J}$ of heat energy from a reservoir at $137°\mathrm{C}$ and rejects $500 \mathrm{J}$ of heat during each cycle, then the temperature of sink is

A Carnot engine absorbs $6\times {10}^5$ cal at ${227}^{o}C.$ The work done per cycle by the engine, if its sink is maintained at ${127}^{o}C$ is

If the efficiency of an engine is $50\%$ and its work output is $500 J,$ then find input.

The volume of an ideal gas is doubled in an isothermal process. Then, which of the following is true?

What is the source temperature of the Carnot engine required to get 70% efficiency? Given, sink temperature $={27}^{\mathrm{o}}\mathrm{C}$ .

When the absolute temperature of the source of a Carnot heat engine is increased by 25% its efficiency increases 80%. The new efficiency of the engine is

For an engine operating between $t_1℃$ and $t_2℃$, the efficiency will be

A Carnot engine is made to work between $200 °\mathrm{C}$ and $0 °\mathrm{C}$ first and then between $0 °\mathrm{C}$ to $-200 °\mathrm{C}$. The ratio of efficiencies of the engine in the two cases is

A Carnot engine has the same efficiency between 800 K to 500 K and $x$K to 600 K. The value of $x$ is

Two heat engines $A$ and $B$ have their sources at 1000 K and 1100 K and their sinks are at 500 K and 400 K respectively. What is true about their efficiencies?

A Carnot engine whose low-temperature reservoir is at $27℃$ has efficiency $37.5\%$. The high-temperature reservoir is at
