A spherical shell is heated. The volume changes according to the equation V_θ = V₀ (1 + γ^θ). Does the volume refer to the volume enclosed by the shell or the volume of the material making up the shell?
Ans : When a spherical shell is heated, its volume changes according to the equation, `` {V}_{\theta }={V}_{0}\left(1+\gamma ∆\theta \right)``. The volume referred to here is the volume of the material used to make up the shell, as its volume expands with the rise of temperature with coefficient of expansion of volume, `` \gamma ``.
