4. The crystalline minerals whose surface activity is such that, they develop cohesion and plasticity are called __________
a) Non-clay minerals
b) Clay minerals
c) Bulky particles
d) Primary minerals
View Answer

6. A montmorillonite platelet has a specific surface/volume equal to ____________
a) 120/μ
b) 100/ μ
c) 500/ μ
d) 1000/ μ
View Answer

Answer: d
Explanation: Since the platelet of montmorillionite has a volume, 5 times greater than equivolume cube (200/ μ) its volume will be equal to 1000/ μ.

7. Which of the following clay minerals are considered as colloidal?
a) Kaolinite
b) Dichite
c) Attapulgite
d) All of the mentioned
View Answer

Answer: d
Explanation: As entire clay particle has a greater dimension than 1μ, all of the clay minerals are considered as colloidal.
