Which of the following is correct option for the free expansion of an ideal gas under adiabatic condition ?

A

`q=0, DeltaT ne 0, W = 0`

B

`q=0, DeltaT ne 0, W ne 0`

C

`q=0, DeltaT = 0, W = 0`

D

`q=0, DeltaT = 0, W ne 0`

Text Solution

Verified by Experts

The correct Answer is:
C
For the free expansion of an ideal gas, the opposing force is zero, hence work done = 0.
`DeltaU=q+w, w=0`, hence `DeltaU=q`
But the process is adiabatic, hence q=0
`therefore q=0, DeltaT=0, W=0`
