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.

Reason: As it is an adiabatic process so q=0 and as it is free expansion of gas is there so w=0.

From the first law of Thermodynamics


ΔU = q + w


This means that ΔU will be 0 which indicates that temperature will remain constant.
