Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula to calculate porosity?
- n = V_voids / V_solids
- n = V_voids / (V_voids + V_solids)
- n = V_solids / V_voids
💡 Hint: Remember, it's a ratio involving total volume.
Question 2
True or False: The value of specific gravity for most inorganic soils is generally less than 2.60.
- True
- False
💡 Hint: Think about how specific weight varies in soil types.
