Question

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

Answer 1

Correct Answer - a
Work done in reversible process is maximum. Thus `T_(2)lt lt T_(1)` in reversible process or `T_(2 rev)lt lt T_(2 irrev)`
