Why do we need an adiabatic expansion in the Carnot cycle? [duplicate]
As we know that 1st process is an reversible isothermal expansion during this the system is in quasi static equilibrium which helps in increasing the volume of the system but why does the second step ...

Reversibility of the ideal Carnot cycle
How do adiabatic processes in the reversible Carnot cycle take place? Is the gas adiabatically isolated? If so, how would that happen in real life? (I know that Carnot cycle is not practically ...

Is an isentropic process always adiabatic? [duplicate]
I am making an exercise about a pulsating jet engine. There is a part in the cycle of this engine that is an isentropic expansion and i'm wondering if I can use $PV^{g} = cte $ in this process

Why does adiabatic expansion occur in the carnot process?
(Spoiler: Why adiabatic expansion happens in Carnot cycle doesn't really answer the question for me.)
In the Carno cycle, the open system is first brought into contact with the warm reservoir, which ...

Why adiabatic expansion happens in Carnot cycle?
$A \rightarrow B$: Isothermal expansion happens. Since the internal energy purely depends on the temperature ($E_{int} = knRT$, $k = \frac{3}{2},\frac{5}{2},3$), then $\Delta E_{int}=0$ in an ...

Is it always true that a non-adiabatic reversible process is an isothermal process?
In a Carnot Cycle, a reversible isothermal process is a non-adiabatic reversible process. Is it always true that a non-adiabatic reversible process is an isothermal process?

What is the need of adiabatic compression in Carnot cycle?
Why do we need to compress the gas adiabatically after the isothermal compression of gas? What if we just skip this step? What will be the consequences? By "skipping this step", I mean, ...

Adiabatic expansion vs. adiabatic compression in Carnot cycle
I am currently studying the Carnot cycle, and am close to understanding it, but something is nagging on my mind. So, during the expansion process of the cycle, work is done on the surroundings as heat ...

Why does adiabatic contraction bring Carnot engine back to initial state? (and other questions) [closed]
I have many questions (all in bold) around the Carnot cycle. I know I'm not the first one to ask a bunch of questions in the middle of a description of my own understanding, but having read other ...

How to find efficiency of a cycle thats not Carnot Cycle?
Here is the Full Question:
A monoatomic gas is expanded adiabatically from volume $V_0$ to $2V_0$ and then is brought back to the initial state through an isothermal and isochoric process respectively....

Why only isothermal and adiabatic for Carnot engine?
What is the reason behind choosing adiabatic and isothermal process for carnot engine?
My book states the following reason. I am not able to understand it. It would be great if you could put it in ...

Is my interpretation of how a Carnot Cycle works correct?
I'm trying to understand how the Carnot cycle works in my learning of it. Here's what I so far believe is what is happening:
(A $\to$ B) A cylinder of gas is connected to a frictionless piston, and ...

Where does the energy come from for adiabatic processes of a Carnot cycle?
I'm getting stuck on where this additional energy comes to move the piston further outward/inward during adiabatic processes when the only energy changed is during isothermal processes. Can someone ...

Understanding why $\int_{T_1}^{T_2}C_Vd\ln(T) + \int_{V_1}^{V_2} nRd\ln(V) = 0$ is violated when $T_2$ and $V_2$ are picked
In Chapter 4 of Chemical Thermodynamics, by Peter A. Rock published by Oxford University Press, 1983, the author is trying to explain why a new state function is needed, specifically a state function ...

Difference between reversible and irreversible adiabatic process in PV diagram
let's say we've got a carnot-cycle in a pressure volume diagram with the following processes:
1 -> 2: reversible isothermal
2 -> 3: reversible adiabatic
3 -> 4: reversible isothermal
4 -> 1: ...
