When two spheres made of the same metal are heated to the same temperature, the coefficient of linear expansion is the same for both spheres.
The formula for volume expansion is given by:
ΔV = γ · V₀ · ΔT
For the solid sphere:
ΔVsolid = γ · Vsolid · ΔT
For the hollow sphere:
ΔVhollow = γ · Vhollow · ΔT
ΔVsolid = ΔVhollow
Hence, the correct answer is Option 1: both spheres will expand equally
