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
Multiple Choice Options
- A (T + 2.4) K
- B (T - 2.4) K
- C (T + 4) K
- D (T - 4) K
Step-by-Step Verified Solution
T 1 = T , W = 6 R j o u l e s , _ = 5 3
W = P 1 V 1 _ P 2 V 2 _ _ 1 = n R T 1 _ n R T 2 _ _ 1
= n R ( T 1 _ T 2 ) _ _ 1
n = 1 , T 1 = T _ R ( T _ T 2 ) 5 / 3 _ 1 = 6 R
_ T 2 = ( T _ 4 ) K
