An ideal gas is allowed to expand both reversibly and irreversibly in an isolated system. If `T_(i)` is the initial temperature and `T_(f)` is the final temperature, which of the following statements is correct?

`(T _(f)) _(rev) = (T _(f)) _("irrev") `

`T _(f) = T _(i)` for both reversible and irrevarsible processes.

`(T _(f)) _("irrev") gt (T _(f)) _(rev) `

`T _(f) gt T _(i)` for a reversible process but `T _(f) = T _(i)` for an irreversible process.

Verified by Experts

The correct Answer is:

In an idela gas, there are no intermolecular forces of attraction. Hence, `T _(f) = T _(i)` for both reversible and irreversible preocesses.
