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 statement is correct ?

Options

A. `(T_(f))_(rev)=(T_(f))_(irrev)`
B. `T_(f)=T_(i)` for both reversible and irreversible process
C. `(T_(f))_(irrev)gt(T_(f))_(rev)`
D. `T_(f) gt T_(i)` for reversible process but `T_(f)=T_(i)` for irreversible process

Answer

B

Explanation

In an ideal gas, there are no intermolecular forces of attraction. Hence `T_(f)=T_(i)` for both reversible and irreversible processes.
