Adiabatic means there's no heat transference during the process;
Isothermal means the process occurs at constant temperature.
The compression and expansion processes are adiabatic, whereas the heat transfer from the hot reservoir and to the cold reservoir are isothermal.
Those are the two adiabatic and isothermal processes.
The Carnot cycle consists of two adiabatic processes, where there is no heat transfer, and two isothermal processes, where temperature remains constant. The adiabatic processes involve compression or expansion of the gas without heat exchange, while the isothermal processes occur at constant temperature with heat exchange. This combination allows the Carnot cycle to achieve maximum efficiency in a heat engine.

What is the carnot statement of the second law of thermodynamics?
The efficiency of a quasi-static or reversible Carnot cycle depends only on the temperatures of the two heat reservoirs, and is the same, whatever the working substance. A Carnot engine operated in this way is the most efficient possible heat engine using those two temperatures
What is the maximum work obtainable from two bodies at temperatures T1 and T2 . i need derivation. pls help you out?
The maximum work obtainable from two bodies at temperatures T1 and T2 is given by the difference in their temperatures multiplied by the change in entropy associated with the process. This is derived from the second law of thermodynamics, specifically the Carnot efficiency equation for a heat engine. The maximum work is represented by the equation: Wmax = (T1 - T2)ΔS.
Is the energy of carnot engine is maximum?
The Carnot engine is the most efficient heat engine possible, but it does not produce maximum energy. It operates between two temperature reservoirs and has an upper limit on efficiency based on those temperatures. The efficiency of a Carnot engine is determined by the difference in temperature between the hot and cold reservoirs.
What is the efficiency of a carnot engine operating between boiling point and freezing point of water?
You must insert the temperatures, in Kelvin, into the formula. Freezing point of water: 273 K; boiling point of water: 373 K. Thus, you get a Carnot efficiency of (373 - 273) / 373, or about 27%.
Whose work on heat engines lead to the formulation of the second law of thermodynamics?
The work of Sadi Carnot, a French engineer, on the efficiency of heat engines in the early 19th century led to the formulation of the second law of thermodynamics. Carnot's insights on the limitations of heat engine efficiency laid the foundation for the development of the second law, which eventually became a fundamental principle in thermodynamics.
Carnot cycle is practically possible or not?
no, a Carnot cycle is not practiclly possible.bcz carnot consist of two cycles. i.e 1-rev. adiabatic 2-isothermal
What is known as carnot heat engin?
carnot's heat heat engine is also known as ideal heat engine.because in carnot's the precess is reversible .Total heat converted into work . The efficiency is maximum for carnot's heat engine.
What are examples of isothermal process?
An isothermal process is a change in a system where the temperature stays constant (delta T =0). A practical example of this is some heat engines which work on the basis of the carnot cycle. The carnot cycle works on the basis of isothermal.
Which cycle consist of two reversible isothermal and isobars?
carnot cycle
Limitations of the Carnot cycle for?
The Carnot Heat Engine Cycle and the Carnot Heat Pump Cycle are reversible cycles and do not exist in any actual operation. However, they are very useful for predicting maximum possible thermal efficiencies and coefficients of performance using the absolute temperature of the heat source and the absolute temperature of the heat sink. The Carnot Cycle consists of two reversible and adiabatic ( isentropic ) steps and two reversible and isothermal steps.
Example of isothermal process?
An example of an isothermal process is when gas expands in a piston cylinder system while being in thermal equilibrium with its surroundings. This means that the temperature of the gas remains constant throughout the process.
Is the volume expanded and the volume compressed during carnot cycle is equal?
Since it is a CYCLE, the overall volume change from minimum volume to maximum volume and back must sum to zero, thus the volume expanded must equal the volume compressed. Now, bear in mind that the Carnot Cycle consists of 4 steps:Reversible isothermal expansion of the gas at the "hot" temperature, T1 (isothermal heat addition or absorption).Isentropic (reversible adiabatic) expansion of the gas (isentropic work output).Reversible isothermal compression of the gas at the "cold" temperature, T2. (isothermal heat rejection)Isentropic compression of the gas (isentropic work input).Although when you graph the cycle on a PV diagram, it looks pretty similar, there is no requirement that the volume change in step 1 matches the volume change in step 3, nor that the volume change in step 2 match that in step 4.
What is the reverse of a carnot engine?
reverse carnot engine is also called a REFRIGERATION SYSTEM.
What are the differene between stirling cycle and carnot cycle?
In Carnot & Stirling cycle there were 2 isothermal processes. but in Stirling engine other 2 processes are constant volume processes whereas in Carnot other 2 processes are isentropic processes. Stirling engine has low maintenance and easy to built because of there construction. Both cycle's efficiencies near to same. but operating according to there applications.
What are the relative advantage of Rankine Cycle over Carnot Cycle in thermal power plants?
Rankine cycle allows for practical implementation with real working fluids such as water, making it more feasible for thermal power plants compared to the idealized Carnot cycle. Rankine cycle also allows for the use of turbines and pumps which are more efficient than isothermal expansion and compression processes in the Carnot cycle. Additionally, Rankine cycle can be modified with reheating and regeneration to improve efficiency further, something the Carnot cycle cannot achieve.
Why is carnot cycle not suitable as an ideal cycle for all power producing cyclic devices?
The Carnot Cycle is a prime example of what is possible under the laws of physics however the cycle is impractical to build. The facts that its keeps stepping back and forth from isothermal to adibatic processes make it very hard to construct.
What is carnot engine in thermodynamics?
A Carnot cycle representes a gas undergoing a theoretical - means it cannot be implemented realistically - thermodynamic cycle composed of 4 reversible steps (meaning you can go back and everything will be back to the state it was, or scientifically speaking, the entropy of the universe will remain constant): 1- isothermal expansion of the gas (working fluid) - heat is added from the surroundings to the working fuild and it expands at constant temperature; 2- isentropic expansion of the gas - the gas is allowed to expand and produce work; 3- isothermal compression of the gas - the gas rejects heat to the surroundings at constant temperature; 4- isentropic compression of the gas - the gas is compressed and work is need for that compression.
