The work done by a closed system in a reversible process is always ___...
Explanation:
Reversible and Irreversible Processes:
- In a reversible process, the system undergoes changes in such a way that it can be restored to its initial state by reversing the process without leaving any trace on the surroundings.
- In an irreversible process, the system undergoes changes in a way that cannot be undone to restore the initial state without leaving a trace on the surroundings.
Work Done in Reversible and Irreversible Processes:
- In a reversible process, the work done by a closed system is the maximum work that can be obtained from the system for a given set of conditions.
- In an irreversible process, the work done by a closed system is less than the maximum work that can be obtained from the system for the same set of conditions.
Comparison of Work Done:
- The work done by a closed system in a reversible process is always greater than the work done in an irreversible process.
- This is because in a reversible process, the system operates in an idealized manner where there are no losses or inefficiencies, leading to maximum work output.
- On the other hand, in an irreversible process, there are losses due to irreversibilities like friction, heat transfer, etc., resulting in lower work output compared to the reversible process.
Conclusion:
- Therefore, the work done by a closed system in a reversible process is always more than that done in an irreversible process due to the differences in efficiency and losses between the two types of processes.
