Question

One mole of an ideal gas at an initial temperature of T K does 6R joules 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
(1) (T + 2.4) K
(2) (T – 2.4) K
(3) (T + 4) K
(4) (T – 4) K

Answer 1

3 one

w=nR(Tf-Ti)/gama-1) is it enough to understand

Answer 2

Answer:

(T+4)K

hope this ans is right

thank you
