Why is the catalyst made porous?
By making the pellets porous, you maximize the surface to volume ratio of the catalyst, which allows you to use less of it, but get the same effect.
How does the porosity affect the amount of water that could stay between rock particles?
Porosity is a measure how hole many pores, or holes a rock has in it. Permeability is a measure of how a rock resists fluids flowing through it. If a rock is very porous and is very permeable, water will pass right through it. Limestone is a good example. If the reverse is true, water will not flow through. Marble or Granite are good examples.
An area in which water travels downward to become part of an aquifer?
Used in geology, hydrogeology, soil science, and building science, the porosity of a porous medium (such as rock or sediment) describes the fraction of void space in the material, where the void may contain, for example, air or water. A rock layer with many particles of different sizes contains much more void space, which means lower porosity.
Is concrete a non-porous surface?
There are two types porous and non porous. You can also seel porous concrete to make it non porous.
How sorting affects porosity?
more sphericity,more porosity good sorting ,more uniform size and more will be the porosity porosity doesnot depend on size of grain
Does clay has a high porosity?
No , it is least porous .
What is porosity and pore size in glass?
No, glass is not porous
Is basalt permeable?
There are 2 types of permeability- Porosity and Perviousness Granite and basalt are both pervious Granite has low porosity, but basalt can be both porous or non-porous. It depends on its rate of cooling.
Is clay porosity higher than sand porosity?
Yes, clay is more porous than sand. Typical porosity of silt and clay is 35-50% and 33-60%, respectively. Sand has porosity of 20-35%.
Are igneous rocks porous?
Igneous rocks generally have extremely low porosity. An exception is pumice, which has abundant vesicles and therefore is very porous (though not permeable).
How and why should a porosity test be carried out?
The reason why a porosity test is important is because hair that is more porous will "suck up" color more quickly than less porous hair. This being said, if the hair is not evenly porous, some parts may be darker than others and vice versa. To test the porosity, simply examine the quality of the hair in your hand. If the ends are severely brittle and porous, you might want to suggest a haircut after the service. Or, to make the porosity more even, apply a developer first, leave on for five minutes (don't wash it out), and then mix the desired color with developer and apply evenly.
What is the porosity of giallo fiorito granite?
Very porous, keep it sealed contantly and blot up all spill imeadiately
What not to do to hair with high porosity?
Porosity refers to your hair's ability to retain moisture. Hair that is highly porous has a raised cuticle that is both quick to absorb and lose moisture. Much highly porous hair is the result of overprocessing, and it is best to avoid chemical and heat processes on such hair in order to prevent futher damage. Instead, using protein treatments will help fill the gaps in the cuticle of porous hair.
What is porosity of hair?
Porous hair absorbs hair chemicals very quickly and can become over process and damaged quickly. On thecontrary, hair that is not very porous does not absorb chemicals very quickly and can be difficult to perm or colour.

Why soil porosity important to farmers?
It is important for soil to hold water for plants to grow, but the soil cannot be so porous that no water is retained for plants to grow in (especially those with shallow root systems), nor can the soil be not porous since plants drown from access to too much water. The majority of crops rely on soils that have some porosity in them versus ones that have no porosity or too much porosity since, for the former, crops like corn and wheat have very shallow root systems that do not grow deep enough to reach water, and for the latter are intolerant of too much water (exceptions are rice patties).
Does porosity affect the strength and properties of building materials?
Yes. Porosity is the void space between grains or clasts of a solid material such as the gaps between the grains in sandstone. Rocks that have higher porosity are typically less stiff at small strain values than more porous rocks as the initial deformation closes up the pore spaces which is relatively easy to do compared to causing deformation of the solid clasts. Pore spaces are also preferential pathways of weakness through a material and as such fractures are more likely to form connecting up porous regions of a solid. As such the more porous a given material, the easier it will be for a fracture to propagate through it. Also porous materials are more likely to contain water which can have a signficant impact by causing significant reductions in the materials the compressive strength.
