A sphere with radius 1 m has temperature 15oC. It lies inside a concentric sphere with radius 2 m and temperature 25oC. The temperature T(r) at a distance from the common center of the spheres satisfies the differential equation

If we let S = dT (dr), then satisfies a first-order differential equation. Solve it to find an expression for the temperature T(r) between the spheres.
