1. A given volume of soil in natural occurrence consists of (a) solid particles only. (b) void spaces occupied by air and/or water. (c) solid particles and void spaces. (d) solid particles and void spaces occupied by air and/or water. 2. A fully saturated soil is generally a (a) one-phase system consisting of soil solids. (b) two-phase system consisting of soil solids and air. (c) two-phase system consisting of soil solids and water. (d) three-phase system consisting of soil solids, water and air. 3. A partially saturated soil is (a) dry soil. (b) moist soil. (c) saturated soil. (d) submerged soil. 4. Which of the following is not a volume relationship? (a) Void ratio (b) Porosity (c) Degree of saturation (d) Water content 5. Porosity of a soil is defined as (a) the ratio of volume of voids to the volume of solids. (b) the ratio of volume of voids to the total volume. (c) the volume of water to the volume of voids. (d) The weight of water to the weight of solids. 6. Which of the following is not represented as a percentage? (a) Void ratio (b) Porosity (c) Degree of saturation (d) Water content 7. Select the incorrect statement. (a) Void ratio can be greater than unity. (b) Porosity lies between 0 and 100%. (c) Degree of saturation lies between 0 and 100%. (d) Water content is always less than 100%. F. If void ratio of a soil is 0.2, then its porosity will be (a) 16.7%. (b) 20.0 %. (c) 25.0 %. (d) none of the above.
