The temperature distribution in sphere with uniform heat generation is given by

T(r)= $\frac{-g_0 r^2}{6k}-\frac{C_1}{r}+C_2$

Where C1 and C2 are constants of integration and can be obtained from boundary conditions

The boundary condition at the centre

At r=0, $\frac{dT}{dr}$ =0

It gives $C_1$ =0

The boundary condition at the surface

At r= $r_0$ , T= $T_s$ …
