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.

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

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

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.

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.

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

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.

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.

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.
