If something is porous, it generally means that it has holes and is absorbent. Some synonyms for porous include penetrable, spongelike and absorptive.
Yes, objects can absorb water if they are porous or have spaces within their structure for water to seep into. Materials like sponge, cotton, and paper are examples of objects that can absorb water.
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.
Some common objects that transmit sound well include solid materials like metal, wood, and glass. These objects allow sound waves to pass through them efficiently, which helps in transmitting sound effectively. Additionally, objects with a smooth surface tend to transmit sound better than rough or porous surfaces.
it is non porous
some types of styrofoam are porous but not all are
glass, plastic, metal. I don't feel like thinking too hard so that is all I will say.
Steel is typically considered non-porous due to its dense and solid structure. However, certain types of steel can have micro-pores or surface imperfections that make them slightly porous. Generally, stainless steel has better resistance to corrosion and is less porous than other types of steel.
There are two types porous and non porous. You can also seel porous concrete to make it non porous.

These are some porous rocks: chalk, limestone, sandstone, pumice, scoria.
