Question

A spherical shell is heated. The volume changes according to the equation Vθ = V0 (1 + γθ). Does the volume refer to the volume enclosed by the shell or the volume of the material making up the shell?

Answer 1

The volume referred is the volume of the material that is used to make up the shell

Explanation:

• The volume of a spherical shell changes when it the spherical shell is heated, according to this equation,
• Vθ = V0 (1 + γ∆θ).  
• Here, the volume referred is the volume of the material that is used to make up the shell, and as when the temperature rises, the volume expands with the coefficient of expansion of volume, γ.
• Vθ = volume of a spherical shell
• ∆θ = change in temperature
• γ = coefficient of expansion of volume
