Q. What makes a thermodynamic process reversible?
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. Throughout the entire reversible process, the system is in thermodynamic equilibrium with its surroundings.
Q. Are all thermodynamic processes reversible?
A thermodynamic process is reversible if the process can return back in such a that both the system and the surroundings return to their original states, with no other change anywhere else in the universe. It means both system and surroundings are returned to their initial states at the end of the reverse process.

Q. How do you know if a process is reversible in thermodynamics?
The criterion for a reversible process would be ΔS=0. The whole point is that the entropy maximum postulate states that the entropy must be maximized.
Q. How do you know if a thermodynamic reaction is reversible or irreversible?
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.
Q. What makes a process irreversible?
An irreversible process is a process that cannot return both the system and the surroundings to their original conditions. Four of the most common causes of irreversibility are friction, unrestrained expansion of a fluid, heat transfer through a finite temperature difference, and mixing of two different substances.
Q. Which of the following is an example of reversible process?
Examples of Reversible Process slow adiabatic compression or expansion of gases. electrolysis (with no resistance in the electrolyte) the frictionless motion of solids. slow isothermal compression or expansion of gases.
Q. What is reversible change with example?
Reversible changes If you can get back the substances you started the reaction with, that’s a reversible reaction. A reversible change might change how a material looks or feels, but it doesn’t create new materials. Examples of reversible reactions include dissolving, evaporation, melting and freezing.
Q. What is the Second Law of Thermodynamics used for?
The second law states that there exists a useful state variable called entropy S. The change in entropy delta S is equal to the heat transfer delta Q divided by the temperature T. An example of a reversible process is ideally forcing a flow through a constricted pipe.
Q. What is the implication of the second law of thermodynamics for living organisms?
One implication of the second law of thermodynamics is that in order for a process to happen, it must somehow increase the entropy of the universe. This may immediately raise some questions for you when you think about living organisms such as yourself.
Q. How is the second law of thermodynamics related to entropy?
The second law of thermodynamics states that the total entropy of a system either increases or remains constant in any spontaneous process; it never decreases. Heat cannot transfer energy spontaneously from colder to hotter, because the entropy of the overall system would decrease.
