4.3: Work and Heat are not State Functions

Figure 19.3.1 : The system is being reversibly and isothermally compressed from state 1 to 2. The amount of work being done on the system is shown by the shaded area. Note that for a compression, a reversible process does less work than an irreversible process. For an ideal gas, the amount of work being done along the reversible compression is:

6: Equilibrium States and Reversible Processes

6.12: Equilibria and Reversible Processes. The distinction between a system at equilibrium and a system undergoing reversible change is razor-thin. What we have in mind goes to the way we choose to define the system and centers on the origin of the forces that affect its energy. For a system at equilibrium, the forces are fixed.

Reversible vs Irreversible

A reversible pathway is a system in equilibrium, so that means internal pressure and external pressure is equal. Work is only done when the external pressure changes, forcing the internal pressure to adjust and maintain equilibrium. Reversible pathways do not have equal external pressure, it will change step-by-step along the path.

reversible vs irreversible

Based on Dr. Lavelle''s lectures, I understood that reversible work expansion was when a system is at equilibrium (in that the internal pressure = external pressure), thus there is an infinitely small change in the volumes and pressures (thus why we use the work equation with the integral). I think then that irreversible work of …

Reversible vs. irreversible processes

Obviously the work performed in the reversible process is larger than the work performed in the irreversible process. Since we could have chosen any condition in Fig. 2.2 the connection between reversibility and maximum work holds quite obviously in general for a perfect gas. As we will see later, taking into account the second law of ...

Reversible and Irreversible Isothermal Expansion of an Ideal

This Demonstration compares the thermodynamic processes of reversible and irreversible isothermal expansion of an ideal gas. The graph and the image of a piston at the top represent the slow expansion of a gas from an initial volume to a final volume (you can vary these volumes with the sliders). Reversible work is given by the integral, which equals …

4.1 Reversible and Irreversible Processes

For an ideal gas, if the internal energy doesn''t change, then the temperature stays the same. Thus, the equation of state of the ideal gas gives us the final pressure of the gas, p = n R T / V = p 0 / 2, p = n R T / V = p 0 / 2, where p 0 p 0 is the pressure of the gas before the expansion. The volume is doubled and the pressure is halved, but nothing else seems to …

The irreversible work depends linearly on the volume and pressure whereas in the reversible work it depends logarithmically but this latest one depends linearly on the temperature. So if you want the reversible work to be less than the irreversible you have to either find a path with a low temperature for the reversible work or with high ...

About Reversible vs Irreversible Gas Compression and Expansion Work

A real-life example of reversible gas compression and expansion is the operation of a reversible heat engine, such as a Carnot cycle. On the other hand, an example of irreversible gas compression and expansion is the operation of a gas turbine, where the compression and expansion processes happen quickly and cannot be fully …

Entropy change in reversible and irreversible processes

A reversible process is one where dSuniv = 0 d S u n i v = 0, while dSuniv > 0 d S u n i v > 0 indicates a (spontaneous) irreversible process. In a reversible process, the entropy change of the system and surroundings are equal and opposite. In an irreversible process, we generate extra entropy. We can assign that "extra" irreversible …

Work in Reversible vs Irreversible Processes

The concept of work done by the gas remains the same in both reversible and irreversible expansions. While the concept of work remains consistent between reversible and irreversible expansions, the methods used to calculate work and the efficiency of the process differ significantly based on the reversibility of the expansion.

Reversible process (thermodynamics)

Overview. Thermodynamic processes can be carried out in one of two ways: reversibly or irreversibly. An ideal thermodynamically reversible process is free of dissipative losses and therefore the magnitude of work performed by or on the system would be maximized. The incomplete conversion of heat to work in a cyclic process, however, applies to both …

Calculating entropy change: reversible vs irreversible process

So, for its alternative reversible path, to achieve this same internal energy change at 300 K, the amount of reversible heat it would have to absorb would be the same 3.741 kJ. So, the change in entropy of the surroundings in the irreversible process was 12.47 J/K. I know that this might all sound a little confusing.
