This paper introduces the 'breathing coefficient' as a tool to analyze volume changes in porous materials, specifically focusing on how volume variations are distributed between solid and void spaces. The application to 2D disc packing swelling provides a concrete example and suggests potential methods for minimizing material expansion. The uncertainty analysis adds rigor to the methodology.
