    Answer:

    4.02×10⁻⁴ K⁻¹

    Explanation:

    Applying,

    γ = (v₂-v₁)/(v₁Δt)…………….. Equation 1

    Where γ  = coefficient of volume expansion, v₂ = Final volume, v₁ = initial volume, Δt = change in temperature.

    From the question,

    Given: v₂ = 850 m³, v₁ = 830 m³, Δt = (90-30) = 60°C

    Substitute these values into equation 1

    γ  = (850-830)/(830×60)

    γ  = 20/(830×60)

    γ  = 4.02×10⁻⁴ K⁻¹
