Question

Assertion (A): The water content of inorganic soils is determined by heating the soil in an oven at a temperature of ${105}^{0}to{110}^{0}C$.
Reason (R): The free water, absorbed water and structural water are all completely removed from the soil by heating it at ${105}^{0}to{110}^{0}C$

• A. both A and R are true and R is the correct explanation of A
• B. both A and R are true but R is not a correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is C A is true but R is false

(c)
The drying of soil is recommended at a temperature of ${105}^{0}to{110}^{0}C$ as temperature than ${110}^{0}C$ may break the crystalline structure of clay particles and result in the loss of chemically bound water of crystallization.
