✦ Synopsis

A perturbation solution IS developed for the movmg boundary probtem mvolvmg the slow growth or dlssolutlon of an isolated sphere This solution resolves the ddlicultles associated with smgular behavior In both space and time. and a space-time matchmg scheme IS used to form urnformly vahd composite solutions for temperature or concentration and for the radms of the sphere The prechctlons of the new solution are compared with a previous analytical solution and with the predIcttons of fimte-ddference solutions
