Coefficient of volume expansion is 8.1 ×10⁻⁴ C⁻¹.
Step-by-step explanation:
The volume expansion of a liquid is given by ΔV,
ΔV = α V₀ ΔT
ΔT = change in temperature = 48.5° C
α = coefficient of volume expansion =?
V₀ = initial volume = 2.35 m³
We need to find α , by plugin the given values in the equation and by rearranging the equation as,

= 8.1 ×10⁻⁴ C⁻¹.
