2. If water content of a soil is 40%, G is 2.70 and void ratio is 1.35, the degree of saturation is- 80%
3. A soil sample of mass specific gravity 1.92 has moisture content 30%. If the specific gravity of solids is 2.75, the void ratio, is- 0.862
4. The ratio of the difference between the void ratio of the soil in its loosest state and its natural void ratio (e) to the difference between the void ratios in the loosest and fully dense state, is generally termed as - Degree of density. Relativity, Density index.
5. The fundamental equation of air content (ac), degree of saturation (Sr) and void ratio (e), is-ace (1-Sr)/(1+e) 6. A moist soil sample weighing 108 g has a volume of 50 cc. If water content is 25% and value of G = 2.52, the void ratio is-0.75
