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 ?

A

`(T_(f))_(rev)= (T_(f))_(irrev)`

B

`T_(f) = T_(i)` for both reversible and irreversible processes

C

`(T_(f))_(irrev) gt (T_(f))_(rev)`

D

`T_(f) gt T_(i)` for revrsible process but `T_(f) =T_(i)` for irreversible processes.

Text Solution

Verified by Experts

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