`1 mol` of `NH_(3)` gas at `27^(@)C` is expanded under adiabatic condition to make volume `8` times `(gamma=1.33)`. Final temperature and work done, respectively, are

A

`150K, 900 cal`

B

`150K, 400cal`

C

`250K, 100cal`

D

`200K, 800cal`

Text Solution

Verified by Experts

`T_(2)= T_(1) ((V_(1))/(V_(2)))^(gamma-1) = 150K`
`w =- C_(V) DeltaT =- C_(V) (T_(2) -T_(1))`
`=- 3 xx 2xx (150 -300)`
`= 900 kcal`
