Which of the three substances has the greatest porosity?

Question

Which of the following three substances exhibits the greatest porosity?
a. Gravel
b. Sand
c. Silt
d. All are equal

Stefan Daugherty · Accepted Answer

Most porous is gravelExplanation: Porosity tells us how much water rock or soil can retain. It tells us about the spaces among the grains. Gravel is more bigger than sand or silt. Its grains are arranged in such a manner that their integral spaces are very bigger so they are more porous. Clay is the most porous but since it is not mentioned in the option so after clay comes the gravel. Usually gravel and sand has equal porosity.

PorosityÂ is a measure of how much of a rock is open space. This space can be between grains or within cracks or cavities of the rock. The substance which has the greatest porosity would be the one that would absorb more water and faster. Hope this helps. Have a nice day.

Three substance has greatest permeability - Option AGravel has the greatest permeability in above options. Permeability depends upon size of particles and degree of saturation. Permeability is the measure of the capacity of a body to promote the development of a magnetic field in itself also it is called as a distributed inductance in Transmission Line Theory. Therefore, it is the level of magnetization that a body gets in answer to an applied magnetic field.
