Morphology

conservation + of + matter

The meaning is directly compositional: 'conservation' (the principle of preserving something) combined with 'matter' (physical substance) yields the scientific principle that matter is preserved or not created/destroyed. The noun phrase pattern 'conservation of X' is regular in scientific vocabulary and has close equivalents in many languages, so a B1 learner who knows the constituents will readily infer the MWE's meaning.

Etymology

Conservation of matter comes from a simple image: imagine a lump of clay you can shape into a cup, a bowl, or a toy, but you never lose any clay, only its shape changes. So, it means 'matter cannot be made or destroyed in a closed box; it only changes form'.
