**Through:** Matter flows within a bounded space, maintaining its volume while conforming to the container's shape.

**Novel properties:**
- maintained volumetric boundary
- variable shape under constraint
- dynamic continuity within containment

## Examples
- The Pacific Ocean maintains its volume despite reshaping daily in Earth's ocean basins due to gravitational tides. *(geophysics)*
- Mercury in a thermometer expands and fills more of the glass column when heated, yet keeps its liquid state at room temperature. *(engineering)*
- Blood plasma circulates in the human body, preserving fluid volume while conforming to vessel shapes during circulation. *(physiology)*
