In thermodynamics , a reversible process is a process whose direction can be reversed to return the system to its original state by inducing infinitesimal changes to some property of the system's surroundings. Having been reversed, it leaves no change in either the system or the surroundings. Since it would take an infinite amount of time for the reversible process to finish, perfectly reversible processes are impossible.

What difference between the two processes in molecular level is responsible for this change? It means an infinitesimal change in something as it undergoes a process. The something of interest here is a thermodynamic state function of a system, its surroundings, or the universe.

When the system undergoes a change from its initial state to the final state, the system is said to have undergone a process. During the thermodynamic process, one or more of the properties of the system like temperature, pressure, volume, enthalpy or heat, entropy, etc. The second law of thermodynamics enables us to classify all the processes under two main categories: reversible or ideal processes and irreversible or natural processes. The process in which the system and surroundings can be restored to the initial state from the final state without producing any changes in the thermodynamics properties of the universe is called a reversible process. In the figure below, let us suppose that the system has undergone a change from state A to state B.

What are Reversible and Irreversible Processes in Thermodynamics?

Hello readers, in this article, we will be going to see the Difference between Reversible Process and Irreversible Process in Thermodynamics and I hope you can clear this concept by reading this paper. So before jumping into the differences, let me give you the general idea of What is Reversible and Irreversible processes in thermodynamics. Reversible Process is a process that can be made to exactly replace its path without suffering any deviation. An irreversible process is a process that cannot be made to exactly retrace its path without suffering its deviation is called an irreversible process. Most of the processes in nature are irreversible. Any process with friction or losses is called an irreversible process. This is the complete explanation about the Difference between Reversible Process and irreversible process which is shown in a detailed manner.

Reversible process (thermodynamics)

One of the most important notions of thermodynamics is the notion of reversible and irreversible processes. A thermodynamic process is defined as a totality of continuously changing states of a thermodynamic system. Two processes can be imagined to develop along the same path between any two states 1 and 2 of a system: from state 1 to state 2 and vice versa, from state 2 to state 1 , the so-called forward and reverse processes. A process is said to be reversible if after the process has been completed in the forward and reverse directions, the system returns into its initial state. Thus, the totality of the forward and reverse processes causes no changes in the surrounding medium.

I asked the professor what the issue is with the answer, and she could not articulate a clear reason, and eventually said she'll re-think it. In a reversible process, at each point along the process path, the system is only slightly removed from being in thermodynamic equilibrium with its surroundings. So the path can be considered as a continuous sequence of thermodynamic equilibrium states.

Figure 1. The ice in this drink is slowly melting. Eventually the liquid will reach thermal equilibrium, as predicted by the second law of thermodynamics. There is yet another way of expressing the second law of thermodynamics. This version relates to a concept called entropy.

  • The basic difference between reversible and irreversible processes is that in the reversible process the system remains in thermodynamic equilibrium, while in the irreversible process the system does not remain in thermodynamic equilibrium. Linda O. - 22.05.2021 at 20:03
  • Summary. A reversible process is one in which both the system and its environment can return to exactly the states they were in by following the reverse path. An irreversible process is one in which the system and its environment cannot return together to exactly the states that they were in. Wendy L. - 23.05.2021 at 02:57
