1.	An ideal gas is allowed to expand both reversibly and irreversibly in an isolated system. If T_(1) is initial temperature and T_(f) is the final temperature, which of the following statement is correct
Answer» `(T_(f))_("irr") gt (T_(f))_("rev")` `T_(f) gt T_(1)` for reversible process but `T_(f)= T_(1)` for irreversible process `(T_(f))_("rev") = (T_(f))_("irr")` `(T_(f))= T_(1)` for reversible and irreversible process Solution :`\|W_("rev")\| gt \|W_("irr")\|, q = 0` (isolated) `RARR` work done at the cost of INTERNAL energy `rArr Delta E lt 0` More energy loss in reversible as more work done in reversible `rArr T_("rev") lt T_("irr")`
