1.	An ideal gas is allowed to expand both reversibly and irreversibly in an an islolated system. If `T_(i)` is the initial temperature and `T_(f)` is the final temperature, which of the following statements is correct ?A. (a) `T_(f)` and `T_(i)` are both reversible and irreversible processesB. `(T_(f))_(irrev)gt(T_(i))_(rev)`C. `T_(f)gtT_(i)` for irreversible process but `T_(f)` and `T_(i)` for irreversible processD. `(T_(f))_(rev)gt(T_(i))_(irrev)`
Answer» Correct Answer - D Work done in reversible process is mamximum. Thus `T_(2)lt lt T_(1)` in reversible process or `T_(i)lt lt T_(f)`
