8.]
L₀ = 1 m
ΔT = 220°C - 20°C = 200°C
α = 0,000012 / °C

L = _ ?

L = L₀(1 + α ΔT)
L = 1(1 + [0,000012 • 200] )
L = 1 + 0,0024
L = 1,0024 m

9.]
V₀ = 1000 cm³ = 10⁻³ m³
ΔT = 220°C - 20°C = 200°C
α = 0,000012 / °C
γ = 3α
γ = 3(0,000012) = 0,000036 / °C

V = _ ?

V = V₀(1 + γ ΔT)
V = 10⁻³(1 + [0,000036 • 200] )
V = 10⁻³(1 + 0,0072)
V = 1,0072 x 10⁻³ m³

10.]
V₀ = 300 cm³ = 3 x 10⁻⁴ m³
ΔT = 40° C - 0°C = 40°C
γ = 0,001 / °C

ΔV = _ ?

ΔV = V₀ γ ΔT
ΔV = 3 x 10⁻⁴ • 0,001 • 40
ΔV = 1,2 x 10⁻⁵ m³
