    0.000182 / °C

    Explanation:

    Thermal volumetric expansion is:

    ΔV = γ ΔT V,

    where ΔV is the change in volume,

    γ is the cubic expansion of coefficient,

    ΔT is he change in temperature,

    and V is the original volume.

    Solving for γ:

    γ = ΔV / (ΔT V)

    Given ΔV = 0.182 cm³, ΔT = 100°C, and V = 10 cm³:

    γ = (0.182 cm³) / (100°C * 10 cm³)

    γ = 1.82*10⁻⁴ / °C

    γ = 0.000182 / °C
