Porosity is the amount of pore space in soils. Permeability is the ability of water to pass through the soil. Why do some soils have high porosity but low permeability?
Some soils have a large volume of pore space,but the individual pores are too small to allowwater to pass through.
Composition porosity permeability particle size are used to describe different types of?
soils
Which will hold more sand gravel or dirt?
sand has more porosity because sand has a very smaller particle size than dirt. relatively, the smaller the particle size, the higher the porosity. clay has the highest porosity than other soils. sand has high porosity. dirt has low porosity
Why do some soils have high porosity but low permeability?
Some soils have a large volume of pore space, but the individual pores are too small to allow water to pass through.
What physical properties are taken care of when classifying the soil?
Physical properties of soils: compressibility, temperature, consistence, permeability, porosity, density, color, electrical resistivity, texture, structure, water absorptivity.

When do you use a porosity test in hairdressing?
a porosity test is done while doing consultation with the client to show how much moisture the hair can absorb.
Why do you carry out a hair porosity test?
Porosity tests are carried out to assess the condition of the cuticle layer of the hair.
When conducting a penetrant test what does the spherical indications on the surface of a part mean?
Porosity
How do you test the acidity of soils?
use a ruler
What is moisture test?
speedy moisture test are use to determine the moisture in the different soils.
