compressibility and Expansibility, sometimes mentioned as "properties," are but results of Porosity.
Evidence of compressibility of gases and incompressibility of liquids.
For water the coefficient of compressibility, or the compression per atmosphere, is about 4.5 10-5.
compressibility and elasticity are evident properties of air.
And so for years we went from "A" to "compressibility" on "horseback."
Mention three illustrations of the compressibility and expansibility of air that you know from your own experience.
Again, let us take an example from Physics—Boyle's law of the compressibility of gases.
Some limits are necessarily imposed upon this compressibility of working effort.
The same is true of the argument drawn from the compressibility of gases.
Resistance to change of extensity: compressibility, porosity, adhesion, cohesion.
