NTR: fluid
The very basic term from physics see the wiki fluid page.
In physics, a fluid is a substance that continually deforms (flows) under an applied shear stress, or external force. Fluids are a phase of matter and include liquids, gases and plasmas. They are substances with zero shear modulus, or, in simpler terms, substances which cannot resist any shear force applied to them.
Fluid, any liquid or gas or generally any material that cannot sustain a tangential, or shearing, force when at rest and that undergoes a continuous change in shape when subjected to such a stress.
Perhaps we could encode it into ENVO as fluid environmental material
Def:
An environmental material which when at rest, continually deforms when subject to an external force or applied shear stress. Fluids comprise material in liquid, gaseous or plasma states of matter.
subclass of environmental material
Making it super class to: gaseous environmental material, liquid environmental material and plasma.
Thoughts?
Should we make a new issue for plasma or do it in this one? I'm in favor of closing this and opening a new issue, to keep things tractable.
