An ideal gas is allowed to expand both reversible 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:

Options

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 reversible process but `T_(f)=T_(i)` for irreversible process.

Answer

C

Explanation

`W_("rev") gt W_("irr")`
