2. A 30 cm sample of dry soil from an aquifer weighs 80 g. When the soil is poured into a graduated cylinder, it displaces 25 mL of water. a. What is the porosity of the soil? b. What is the average density of the soil particles?
3. A soil's porosity is (a. ) related to its bulk density and (b. ) with increases in organic matter content. We have to interpret soil porosity with caution because it is a (c. ) variable (does not include time in the denominator) and tells us little about the (d. ) of water through the soil pores. a: b: c: d:
A soil sample has a gravity density of 22 kN / m3 and a water content of 10%. What is the dry gravity density of the sample? If the dry density, wet density and grain density of a soil sample are 1.6 g / cm3, 1.84 g / cm3 and 2.56 g / cm3, respectively, what will be the porosity of the sample?
