💡 Solution & Explanation

Reversible adiabatic expansion produces the maximum possible work. Since adiabatic work is done at the expense of internal energy ($\Delta U = W$), the system loses more internal energy reversibly than irreversibly, resulting in a larger temperature drop (lower final temperature). Statement II is the correct thermodynamic explanation for Statement I.
