Pores [in Physics]

Pores [in Physics]
small interstices or void spaces between the particles of matter, that constitute every body, or between certain aggregates or combinations of them.
Mr. Boyle in his essay on the porosity of bodies, proves that the most solid bodies that are, have some kind of pores; and indeed if they had not, all bodies would be alike specifically weighty.
