Answer:
7.66×10⁻⁵ K⁻¹
Explanation:
From the question,
γ = (v₂-v₁)/[v₁(t₂-t₁)]....................... Equation 1
Where γ = coefficient of volume expansion, v₁ = initial volume, v₂ = Final volume, t₁ = initial temperature, t₂ = Final Temperature.
Given: v₁ = 26.1 cm³, v₂ = 26.2 cm³, t₁ = 25 °C, t₂ = 75 °C.
Substitute these values into equation 1
γ = (26.2-26.1)/[26.1(75-25)]
γ = 0.1/(26.1×50)
γ = 0.1/1305
γ = 7.66×10⁻⁵ K⁻¹
Hence the coefficient of volume expansion is 7.66×10⁻⁵ K⁻¹
