mesostate

noun4

1. •
   A composite state of a physical system that is determined by the overall configuration of many microstates; e.g. the heat of a substance (mesostate), which is made up of the aggregate of motions of many molecules (microstate).

   • If the manipulation is slow enough, and the driving connects different mesostates, then jumps between states in the same mesostate satisfy the detailed balance condition. — 2021
2. •
   A description of an aspect of a geographical system at a level between complete detail (the microstate) and a simple summary statistic or percentage (the macrostate).
3. •
   An intermediate physical state of matter between solid and liquid, in which the molecules have more freedom of movement than when locked in a crystal lattice, but less freedom of movement than when in the liquid state.
4. •
   (rare) An intermediate metabolic product in the formation of anastates or catastates.
