    Explanation:
    For free expansion of ideal gas,
    Pext = 0
    WpV = 0
    For adiabatic process, 
    q = 0
    Conclusion:
    Thus, the condition for free expansion of an ideal gas under adiabatic condition is q = 0, w = 0, ΔT = 0.

    The condition for free expansion of an ideal gas under adiabatic condi...
    Explanation:

    Free Expansion of an Ideal Gas:
    In free expansion, an ideal gas expands into a vacuum, doing no work on the surroundings and experiencing no change in temperature. This process is adiabatic since there is no heat transfer involved.

    Conditions for Free Expansion:
    The conditions for free expansion of an ideal gas under adiabatic conditions are as follows:
    - q = 0: No heat is exchanged with the surroundings during free expansion.
    - w = 0: No work is done by the gas on the surroundings during free expansion.
    - ΔT = 0: There is no change in temperature of the gas during free expansion.

    Correct Answer:
    Therefore, the correct condition for free expansion of an ideal gas under adiabatic conditions is: q = 0, w = 0, ΔT = 0 (Option A). This means that no heat transfer, no work, and no change in temperature occur during the process of free expansion.
