In an adibatic process, no transfer of heat takes place between system and surroundings. Choose the correct option for free expansion of an ideal gas under adiabatic conditions from the following :

A

`q=0 , DeltaT cancel(=) 0,w=0`

B

`q cancel(=) 0, DeltaT =0,w=0`

C

`q =0,DeltaT=0, w=0`

D

`q=0,DeltaT=0,w cancel (=) 0`

Text Solution

Verified by Experts

The correct Answer is:
c
For free expansion , `P_(ext) = 0,w = - P _(ext) DeltaV=0`
For adiabatic process , `q=0`
`:. DeltaU =q+w= 0`. This means that internal energy remains constant which is so at constant temperature. Hence `DeltaT =0`
