Interparticle Force in a Soil Mass
1 - Question
There are _________ possible type of attractive forces.
a) 4
b) 5
c) 6
d) 2
View Answer
Explanation: There are 6 types of attractive forces.
i) vanderwaal’s London force ii) hydrogen
iii) bond, cationic linkage
iv) di-pole cationic linkage
v) water dipole linkage
vi) ionic bond.
2 - Question
Which of the following type of attraction force act between two-particle carrying negative charges?
a) Vander Waal’s London force
b) Water-dipole linkage
c) Ionic bond
d) Cationic linkage
View Answer
Explanation: The cationic linkage act as bridge between two adjacent particle carrying negative charges.
3 - Question
The repulsive force between the soil colloids become effective when?
a) They approach other
b) They combine with each other
c) They are at a distance
d) They overlap
View Answer
Explanation: When two soil colloids approach each other close enough, the double layer tend to overlap and interact.
4 - Question
Which of the following, is considered to be a universal attractive force?
a) Gravitational force
b) Dipole-cationic linkage
c) Ionic bond
d) Vander Waal’s London force
View Answer
Explanation: Since the vanderwaal’s London force effective in many soils, where other is not it is considered as a universal attractive force.
5 - Question
The type of bond in kaolinite crystal is _____________
a) Cationic linkage bond
b) Hydrogen bond
c) Linkage bond
d) Ionic bond
View Answer
Explanation: The edges of two kaolinite crystal are joined by two cations. Hence cationic linkage bond exist in kaolinite crystal.
6 - Question
The repulsive force in soil particle is due to ____________
a) Particles are attracted to each other
b) Particles are similarly charged
c) Particles are oppositely charged
d) None of the mentioned
View Answer
Explanation: Since the particles are similarly charged (negative) they repel each other causing repulsive force.
7 - Question
The cationic linkage is similar to the intersheet bonds of ____________
a) Kaolinite
b) Illite
c) Dichite
d) Montmorillonite
View Answer
Explanation: The cationic linkage is similar to the intersheet bonds of illite since particle can be linked together through water-cation-water mechanism.
8 - Question
Between the soil particles, the cation charge may be entirely balanced by ____________
a) Particle repulsion
b) Negative charge
c) Cationic charge
d) Particle charge
View Answer
Explanation: The cation may be entirely balanced by particle charge so that there is no cation-cation repulsion.
9 - Question
There is no strong repulsive force between soil particles because ____________
a) Mobile cation will move along the surface
b) Cation will move opposite to each other
c) Cations replace each other
d) None of the mentioned
View Answer
Explanation: The mobile cations will move along the particle surface of positions which is balanced by particle charge there. Therefore repulsive force does not exist.
10 - Question
The gravitational force between two soil particle is ____________
a) Proportional to charge
b) Proportional to area
c) Proportional to mass
d) Proportional to surface
View Answer
Explanation: When the mass of the particle increases, the gravitational force acting downward on the particle increases. Hence both mass and gravitational force are proportional to each other.
