Physics - Heat & Thermo Question with Solution | TestHub

A highly thin conducting spherical shell of radius ${\mathrm{R}}_0$ is completely filled with water at $0^{\circ }\mathrm{C}$. Outside surrounding temperature is $-{\mathrm{T}}_0{}^{\circ }\mathrm{C}$. Latent heat of fusion of water is ${\mathrm{L}}_0$ and thermal conductivity of ice is ${\mathrm{K}}_{\text{ice }}$. Assume heat is flowing symmetrically in radial direction. Choose the CORRECT option(s). Density of water is ${\rho }_0$. Neglect the expansion of water on freezing.
