Now the possibility of translation implies the existence of an invariant.
We again obtain, therefore, the invariant system ice—salt—solution—vapour.
If triangles and genera are of our own production we can keep them invariant.
At this point there exists the invariant system solid nitrile, two liquid phases, vapour.
But relations between invariant objects will themselves be invariant.
Since the cryohydric point is a quadruple point in a two-component system, it represents an invariant system.
What now is the nature of this invariant it is easy to understand, and a word will suffice us.
K is also an invariant point at which potassium iodide is in equilibrium with two liquid phases and vapour.
She is the invariant of each of her iconic Mantrams and her surroundings are the variables that enter and leave the screen.
At this point the system is invariant, and the pressure will therefore remain constant until all the iodine has disappeared.
