PART A (Answer any THREE questions in PART A) a Q.1(a) In a natural state, a moist soil has a volume of 0.0082 m and a mass of 17 kg. After oven dry, the soil has a mass of 14.75 kg. If the specific gravity of the soil is 2.65, determine the following properties of the soil: (0) mass of water (Mw); (ii) moisture content (w); bulk density ((pb); (iv) dry density (pdry); (v) volumes of air (V.), water (VW) and solid grain (V): (vi) air void ratio (Av); (vii) void ratio (e); (viii) porosity (n); (ix) degree of saturation (S.); additional water mass required to achieve 100% saturation of the soil; (xi) saturated density (psnt); and (xii) submerged density (sub).
