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.
Porosity refers to the amount of empty space that is between particles of material. When something has a low porosity, it does not have much of this space between its particles.

A catalyst is a substance that increases the rate of a reaction without being used up. Some catalysts work by giving the the reacting particles a surface to stick to where they can make contact which increases the amount of collisions between the particles. Therefore a catalyst effects collision theory by speeding up a reaction.
Particles in a liquid have only a small amount of space between each other. They have more energy then solid particles but less energy than gas particles. Particles in liquid roll over each other this is what causes water to flow.
semi-permeable
Porosity refers to the amount of empty space that is between particles of material. When something has a low porosity, it does not have much of this space between its particles.
The larger the particle size, the higher the porosity. Also keep in mind that angular particles have a higher porosity than round particles. *Good way to remember porosity is that the spaces between particles are "pore-like."
high porosity
A piece of sand on the beach in Miami and onh on a beach in Japan have the whole earth between them.
"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 ..........
The voids present between the soil particles are called pore space and the size of these pores depends on whether the ore is between the soil particles or between the soil aggregates. In general, in cultivated lands, soil particles do not exist as single grains and therefore, there are only voids within the soil aggregates or peds and voids between the aggregates. As clay particles play a major role in the formation of soil aggregates by way of binding the soil particles, the particles within the aggregates are micro pores and between the aggregates are macro pores. Depending on the amount of clay particles, the proportion of micro to macro pores may vary and in most cases the soils containing more clay particles favour aggregation and thereby the micro pores and total porosity.
Factors that affect Coulomb's Law includes the particle charge and the distance between the charges. Coulomb's Law states that the force between the charged particles is related to the amount of charge each of the particles carries.
size of the particles in the material shapes and uniformity of the material amount of cementing agent in the pore space of the material All of the above are correct.
As the space changes between the particles, so does the state of matter.
The relationship between density and porosity is an indirect proportionality.That is, the higher the density of a rock, the lower will be the porosity of that rock.In a more explicit way, the weight of over-lying rocks increase the density of the rock beneath, which in turn decreases the amount of pore spaces (porosity) of the rock through processes such as compaction, cementation, etc. Posted by Nwigwudu Ikechukwu.

The amount of space that gas particles can take up is the size of the container, but the amount between them also is determined by the amount of space the gas takes up.
