Expert Answer - You have a 100 cm3 sample of soil A

1. You have a 100 cm3 sample of soil A. The sample is oven dried and weighed. The weight is 160 g.
What is the bulk density of soil A?

What is the % porosity of soil A? 


2. You have a 100 cm3 sample of soil B. The sample is oven dried and weighed. The weight is 120 g.
What is the bulk density of soil B? 
What is the % porosity of soil B? 
Which soil (A or B) can hold more water when saturated? 

3. You obtain a soil sample with a volume of 400 cm3. It has a moist weight of 450 g and an oven- dry weight of 400 g. Determine the soil bulk density, the porosity, the volumetric water content and the gravimetric water content.

4. You obtain a soil sample with a volume of 400 cm3. It has a moist weight of 450 g and an oven- dry weight of 350 g. Determine the soil bulk density, the porosity, the volumetric water content and the gravimetric water content.

5. You obtain a soil sample with a volume of 200 cm3. It has a moist weight of 250 g and an oven-dry weight of 200 g. Determine the soil bulk density, the porosity, the volumetric water content and the gravimetric water content.
