No, the process is reversible by default but can be made reversible using elements like regenerator.

It is a polytropic process, p is pressure, we is volume and n is polytropic index.

Answer is wrong. It is also reversible process. So false is correct answer.

How we can say that all of above is irreversible process? please tell me.

Saddam Husain said:   7 years ago
Above processes can be made reversible with the help of a regenerator.

Except throttling and free expansion, all are reversible processes.

Mahesh kumar said:   7 years ago
Incorrect is the answer because all these processes are reversible.

Shrikrishna said:   8 years ago
The Correct answer is false. Because all are a reversible process.

Rajeev said:   9 years ago
Only throttling process is irreversible, so, the answer is false.

pvn mean pv power n in which the process is polytropic.
