Modes of Occurrences of Water in Soil

Question 1
Marks : +2 | -2
Pass Ratio : 100%
Based on inter-particle forces, soil water can be classified in to __________
Adsorbed water
Pore water
All of the mentioned
None of the mentioned
Explanation:
Adsorbed water which is attracted by forces within the soil and pore water are the two types of soil water divided based on inter-particle forces.
Question 2
Marks : +2 | -2
Pass Ratio : 100%
Hygroscopic water is affected by which of the following factor?
Gravity
Capillary forces
All of the mentioned
None of the mentioned
Explanation:
Since hygroscopic water has greater density and viscosity than ordinary water. It is neither affected by gravity or capillary forces or by any other force.
Question 3
Marks : +2 | -2
Pass Ratio : 100%
The soil water which is impossible to remove from the soil is ___________
Structural water
Capillary water
Solvate water
Pore water
Explanation:
Under loading encountered in soil engineering, it is found out that structural water cannot be separated or removed and therefore it is considered as a part and parcel of the soil particle.
Question 4
Marks : +2 | -2
Pass Ratio : 100%
Solvate water is subjected to __________ forces.
Polar
Electrostatic
Binding
All of the mentioned
Explanation:
Since the solvate water forms a hydration shell around soil grain. It is influenced by ionic and polar forces.
Question 5
Marks : +2 | -2
Pass Ratio : 100%
Ground water is influenced by ____________ force.
Vander Waals force
Surface force
Hydrodynamic force
Electro static force
Explanation:
As the ground water obeys laws of hydraulic force, it is capable of moving under hydrodynamic forces.
Question 6
Marks : +2 | -2
Pass Ratio : 100%
Ground water may be also called as ___________
Capillary water
Gravitational water and Free water
None of the mentioned
All of the mentioned
Explanation:
Since the ground water is subjected to no forces other than gravity. Hence the water is also known as gravitational water or free water.
Question 7
Marks : +2 | -2
Pass Ratio : 100%
What are the forces involved in hygroscopic water or contact moisture?
Adhesion force
Capillary force
All of the mentioned
None of the mentioned
Explanation:
In hygroscopic water, soil particle freely adsorbs water from the atmosphere by the physical force of attraction, and is held by adhesion force.
Question 8
Marks : +2 | -2
Pass Ratio : 100%
Water present in the voids of soil mass is called __________
Soil water
Free water
Ground water
Pore water
Explanation:
Soil water is the water present in the voids of the soil mass.
Question 9
Marks : +2 | -2
Pass Ratio : 100%
The water which soaks in to ground by moving downward, subjected to capillary force is ___________
Ground water
Pore water
Infiltrated water
Capillary water
Explanation:
Infiltrated water is the portion of surface precipitation which soaks into ground moving downward through air-containing zones.
Question 10
Marks : +2 | -2
Pass Ratio : 100%
The average hygroscopicity of clay is ___________
6 %
16 %
1 %
4 %
Explanation:
The average hygroscopicity of sands, silts and clay is 1 %, 6 % and 16 %.
