Response Details:


    Initial volume = V

    Coefficient of volume expansion = γ

    Change in temperature = Δt

    Change in Volume , ΔV = γ V Δt

    Here, 'V' and 'Δt' are same for all

    Hence, Change in volume is directly proportional to the Coefficient of Volume expansion

                ΔV  α  γ

    As, helium has large 'γ' value among the given materials, the contraction is most in the case of helium
