Q.
In an adiabatic process, no transfer of heat takes place between system and surroundings. Choose the correct option for free expansion of an ideal gas under adiabatic condition from the following.
q=0,ΔT=0,W=0
For free expansion, W=0
For an adiabatic process, q=0
Therefore, from first law of thermodynamics, ⇒ Internal energy (ΔU)=q+W
As q and W, both are o, ∴ΔU=q+W=0+0=0
As there is no change in internal energy, temperature will also remain constant. ∴ΔT=0
