Specific surface is termed as__________
Specific surface is usually defined as the total surface area of the soil particle in a unit mass.
Specific surface of the soil particle increase very rapidly ,as the grain size____________
The subdivision of a mass yields greater surface area, than the same mass itself. Specific surface of a mass increases as the grain size decreases.
A factor, which is important for the magnitude of specific surface of soil particles is__________
Specific surface varies for different shapes of particle having the same mass. Hence grain shape is important factor for determining specific surface.
The specific surface of a soil particle will be___________
The electrical force responsible for inter-particle effect is proportional to the specific surface.
The harmonic diameter, can be found out by using__________
The harmonic diameter DH can be found by using kozney’s method using the formula
Specific surface of a soil is related with__________
As specific surface is associated with surface characteristics of a particle, therefore it is related with physical properties.
Microscopic soil particles have a very___________
As the specific surface increases as the size of the grain decreases .Therefore Microscopic particles have a large specific surface.
specific surface(SS) can also expressed as________
From the expression, specific surface = surface area of particle/volume of particle ,it can be seen that specific surface is the surface area of a particle.
Permeability of the soil depends on__________
Permeability of soil greatly depends on specific surface of the soil because of the viscous effects associated with surface characteristics of the grains.
Chemical activity of a clay mineral depends on__________
The chemical activity of the clay mineral depends upon the surface area, because of the electrical charge of clay minerals is high per unit mass.
