AIPMT 2004 | Heat and Thermodynamics Question 77 | Physics

One mole of an ideal gas at an initial temperature of T K does 6R joule of work adiabatically. If the ratio of specific heats of this gas at constant pressure and at constant volume is 5/3, the final temperature of gas will be

(T + 2.4) K

(T $$-$$ 2.4) K

(T + 4) K

(T $$-$$ 4) K
