`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

`Delta H gt Delta U`

B

`Delta U gt Delta H`

C

`Delta U =4.1 KJ`

D

`Delta U= 4.0001 KJ`

Text Solution

Verified by Experts

The correct Answer is:
B, D
`Delta H= 4KJ`
`Delta H=Delta U+Delta(PV)`
`Delta U= 4-P(V_(2)-V_(1))=4-(10^(5)(18-19)xx10^(-6))/(10^(3))= 4+1xx10^(-4)=4.0001 KJ`
