Answer: b) Ratio of the volume of air voids to volume of total voids in the soil mass
Explanation:
The volume of air voids to the volume of total voids in soil mass is called air content.
Air content is related to the degree of saturation.
When we subtract the value of the degree of saturation from one, we will get the air content value in the soil sample.
i.e., ac =1-S.
ac = Va / Vv
Where,
- Ac = Air Content
- Va = Volume of air
- Vv = Volume of void
- S = Degree of saturation
