Question

One mole of an ideal gas at an initial temperature of T K does 6 R joules of work adiabatically. If the ratio of specific heats of this gas at constant pressure and at constant volume is 35 , the final temperature of gas will be

• A. (T –2.4) K
• B. (T + 4)K
• C. (T – 4) K
• D. (T + 2.4)K

Answer 1

Answer: (C)

(T – 4) K

Answer 2

The final temperature of the gas will be the same as the initial temperature, which is T Kelvin.
