"porous"
the material is in an enclosed package so you would never know what the material is through basic means of deduction such as all five senses.
One of the customers of a material engineer is an electrical engineer. To understand the customer and what he wants, a good material engineer needs to learn the basics of how to communicate with the customer. Engineers communicate through drawings so that means a material engineer needs to learn how to read/create electrical drawings.
The material comprises a fabric (typically a polyfluorinated polymer) that is water repellent, but which has microscopic holes in it. Microscopic drops of water from sweat, and water vapour itself, are small enough to get through the holes. Larger drops of water, such as those in rain, are too large to get through the holes, and so sit on the surface, experiencing the water-repellent properties of the material. It's by no means the same thing, but it's rather like the fact that sugar can pass through a sieve, whereas sugar lumps can't.
it means how tough the material is. duh. \ NOPE! JUST CHUCK TESTA WITH ANOTHER REALISTIC ANSWER! 8======D

Perfusion - passing of a fluid through space
Transparency means that the photons are not affected (except for speed) by that material.
That means that part of the wave is absorbed by the material.
An impervious rock is one that does not allow water to flow through it. It has no air spaces and has no way of storing water at all.
"Porosity" can be used to refer to voidage of a granular material. Pporosity could also denote the relative volume of pores, cracks and spaces in the solid body, while voidage deals exclusively with the amount of spaces between particles in relation to the overall volume occupied by the granular material. Porosity is measure of void spaces in a material.voidage means the relative amount of space between materials that are tightly packed ..........
Sponges are filter feeders. This means that they pull water through their bodies and eat whatever they can filter out of it. The more folds and spaces that a sponge has, the more spaces there are for it to filter. This is the reason that sponge bodies are full of holes and spaces.
A material that something passes through. For example vibrations traveling through a metal rod. The metal rod is the medium.
it means current can pass through it e.g metal. and a non-conductive material is where current cant pass through it (so its resistance is infinitive) e.g plastic or rubber.
There are two words with different meanings. POROUS - there are spaces through which gas or liquid can enter the material. (This actually applies to any surface having "pores" or openings.) PERMEABLE - gases or liquids can pass through (sometimes only some particular ones)
Exocytosis is the transport of material out of a cell by means of a sac or vesicle that first engulfs the material and then is extruded through an opening in the cell membrane.
The purpose of clear cards is to be able to be seen through which means that they must be made of a transparent material. One such available material would be plastic.
Sound waves can travel through any compressible material (which means any real material), be it solid, liquid, or gas. Sound waves cannot travel through a vacuum.
