Answer:
a. ΔV = 0.48895 gal
b. ΔV = 1.246 gal
Explanation:
V₀ = 55.0 gal
β₁ = 11 x 10 ⁻⁶ (° C) ⁻¹
β₂ = 9.0 x 10 ⁻⁴ (° C) ⁻¹
a.
ΔT = 10.0 ° C
ΔV = (β₁ - β₂) * V₀ * ΔT
ΔV = [ 9.0 x 10 ⁻⁴ (° C) ⁻¹ - 11 x 10 ⁻⁶ (° C) ⁻¹ ] * 55.0 gal * 10 ° C
ΔV = 0.48895 gal
b.
ΔT = 25.5 ° C
ΔV = (β₁ - β₂) * V₀ * ΔT
ΔV = [ 9.0 x 10 ⁻⁴ (° C) ⁻¹ - 11 x 10 ⁻⁶ (° C) ⁻¹ ] * 55.0 gal * 25.5 ° C
ΔV = 1.246 gal
