A porous barrier is a barrier against the movement of one type of objects that is not a barrier to the movement of another type of objects. A "real life" example would be a picket fence, which stops motion of objects, such a s adult humans, that are larger than the distance between the pickets but not those of smaller objects such as snakes and insects. However, the most common use of the phrase is in engineering and physical chemistry, specifically in osmosis and reverse osmosis technology, battery design, and other electrochemistry. In these fields, porous barriers have been devised that permit the flow of water but not electrolytes, of cations but not anions, etc.

Is metal porous?
Metal is not porous. Many other elements are porous though and when metal combines with them it can potentially become porous.
What does non-porous mean?
Porous means 'with holes'. So non-porous means 'without holes'
Definition of porous and non porous materials?
Porous means, containing pores ie, small or tiny hole, while non-porous means, without pores or holes.
How many types of barriers of communication are there?
There are many types of barriers of communication for example; language barrier, physical barrier, emotional barrier, listening barrier, cultural barrier, gender barrier etc
Why must an eggshell be porous?
for oxidation
What is it called when you use a porous barrier to separate solids?
Filtration.
Can filtration to separate solids from liquids by using a porous barrier?
Yes, that's what filtration is.
What has the author A F Brown written?
A. F. Brown has written: 'Partial separation of the uranium isotopes by diffusion through a porous barrier' 'A flow meter for small gas flows'

Is polystyrene a good sound insulator?
Polystyrene is neither sufficiently porous nor of sufficient mass to be either a good Sound Absorber, or a Sound Barrier. [Those are the proper technical terms.]
Is silk porous or nonporous?
Silk is porous -- it absorbs liquids.
Is metal porous?
Metal is not porous. Many other elements are porous though and when metal combines with them it can potentially become porous.
Does metamorphism make the rock more porous or less porous?
more porous
How long will it take 10.0ml of nitrogen gas to enfuse through a porius barrier if it has been observed that 92.1 minutes are required for 10.0mL of Cl2 gas to enfuse through the same barrier?
The rate of gas diffusion through a porous barrier is inversely proportional to the square root of its molar mass (that is, a gas four times as heavy diffuses half as fast). The rest is simple arithmetic.
What a good sentence for porous?
The story proved to be quite porous. Lava is a porous rock.
