What is Carnot cycle Class 11?
Cycle of processes in a Carnot engine
Engine absorbs heat Q1 at temperature T1. An adiabatic process takes place inside the engine because of which there is increase in the temperature of the engine from T1 to T2 but no flow of heat. As system is releasing heat so it is isothermal contraction.
What are the four process of Carnot cycle? 7.3. The four stages in the Carnot cycle. (A) Stage 1: Isothermal expansion under heat input Q1, (B) Stage 2: Adiabatic expansion accompanied by a fall in temperature T1 to T2, (C) Stage 3: Isothermal compression, Q2 exhausted, (D) Stage 4: Adiabatic compression accompanied by an increase in temperature T2 to T1.
What is Carnot cycle explain?
Carnot cycle, in heat engines, ideal cyclical sequence of changes of pressures and temperatures of a fluid, such as a gas used in an engine, conceived early in the 19th century by the French engineer Sadi Carnot. It is used as a standard of performance of all heat engines operating between a high and a low temperature.
What is the efficiency of a Carnot engine?

What is Carnot engine and its principle?
Carnot's theorem, developed in 1824 by Nicolas Léonard Sadi Carnot, also called Carnot's rule, is a principle that specifies limits on the maximum efficiency any heat engine can obtain. The efficiency of a Carnot engine depends solely on the temperatures of the hot and cold reservoirs.
What is the principle of Carnot heat engine?
The Carnot principle states that the reversible heat engines have the highest efficiencies when compared to irreversible heat engines working between the same two reservoirs. And the efficiencies of all reversible heat engines are the same if they work between the same two reservoirs.
What is meant by Carnot cycle?
Definition of Carnot cycle
: an ideal reversible closed thermodynamic cycle in which the working substance goes through the four successive operations of isothermal expansion to a desired point, adiabatic expansion to a desired point, isothermal compression, and adiabatic compression back to its initial state.
What is a Carnot engine explain the Carnot cycle with a diagram Class 11?
Solution : A carnot engine is an engine converting heat energy into mechanical energy using a cyclic process consisting of two isothermal and two adiabatic reversible process. <br> OR <br> A heat engine based on carnot cycle is known as carnot engine which works between two temperature.
What is Carnot engine class 11?
A Carnot engine is named after Carnot scientist. It is a reversible heat engine operating between two temperatures. It has a maximum efficiency which no other engine can have.
The efficiency is 100% only when T2 is zero or T1 is infinite. This is not possible since some amount of heat gets rejected to the sink. Was this answer helpful?
It can be 1 or 100% only when TL = 0K (absolute zero of temperature) which is impossible to attain practically. 2. The efficiency of the Carnot's engine is independent of the working substance. It depends only on the temperatures of the source and the sink.
There are several types of thermodynamic processes, including (a) isothermal, where the system's temperature is constant; (b) adiabatic, where no heat is exchanged by the system; (c) isobaric, where the system's pressure is constant; and (d) isochoric, where the system's volume is constant.
Thermodynamic processes include (a) isothermal, in which the system's temperature remains constant; (b) adiabatic, in which no heat is exchanged; (c) isobaric, in which the system's pressure remains constant; and (d) isochoric, in which the system's volume remains constant.
The Carnot cycle consists of the following four processes: A reversible isothermal gas expansion process. In this process, the ideal gas in the system absorbs qin amount heat from a heat source at a high temperature Thigh, expands and does work on surroundings. A reversible adiabatic gas expansion process.
The efficiency of a Carnot cycle is determined only by the temperatures of the hot and cold reservoirs and is calculated using the Carnot efficiency equation: η=1−TCTH η = 1 − T C T H .
Thermodynamics. Principle of heat engine. A heat engine is a device that converts heat to work. It takes heat from a reservoir then does some work like moving a piston, lifting weight, etc, and finally discharging some of the heat energy into the sink. In each engine, there is one working substance.
The Carnot theorem states: No heat engine operating on a cycle between two heat reservoirs at different fixed temperatures can be more efficient than a reversible engine. Two reversible heat engines operating between two heat reservoirs at different fixed temperatures will have the same efficiency.
The Carnot engine is a theoretical thermodynamic cycle proposed by Leonard Carnot. It estimates the maximum possible efficiency that a heat engine during the conversion process of heat into work and, conversely, working between two reservoirs can possess.
Carnot engine is a theoretical thermodynamic cycle proposed by Nicolas Léonard Sadi Carnot in 1824. Carnot states that a hot body is required that generates heat and a cold body to which the caloric is conveyed, which produces mechanical work in the process.
It is impossible for heat engines to achieve 100% thermal efficiency () according to the Second law of thermodynamics. This is impossible because some waste heat is always produced produced in a heat engine, shown in Figure 1 by the term.
(i) Isothermal process : It is a thermodynamic process which occurs at a constant temperature. (ii) Isobaric process : It is a thermodynamic process which occurs at a constant pressure. (iii) Isochoric process : It is a thermodynamic process which occurs at a constant volume.
ii Isobaric process : It is a thermodynamic process which occurs at a constant pressure. iii Isochoric process : It is a thermodynamic process which occurs at a constant volume. iv Adiabatic process : It is a thermodynamic process in which there is no exchange of heat between the system and surroundings.
An isothermal process is a thermodynamic process in which the temperature of a system remains constant. The transfer of heat into or out of the system happens so slowly that thermal equilibrium is maintained.
Thermodynamics eBook: The Carnot Cycle. A process is reversible if, after it has been carried out, it is possible to restore both the system and its entire surroundings to exactly the same states they were in before the process.
