When an ideal gas is suddenly allowed to expand adiabatically into an evacuated container, then

A

`Delta S = 0`

B

`Delta G = 0`

C

`Delta U = 0`

D

`Delta G = - T Delta S`

Text Solution

Verified by Experts

The correct Answer is:
C
For adiabatic process, q = 0
For expansion against vacuum, w = 0
:. `Delta U = q + w = 0`
