A soil sample has a porosity of 40%. What does this mean?
A. 40% of its weight is water
B. 40% of volume is voids
C. 40% is composed of clay
D. 40% of air has escaped
Answer: Option B
Solution (By Examveda Team)
Porosity is the ratio of void volume to total volume.A porosity of 40% means 40% of the soil's volume is voids (air + water).This Question Belongs to Geological Engineering >> Soil Mechanics
