Question 1
What is the relationship between void ratio and porosity?
- e = n/(1-n)
- e = 1/n
- e = n+n
💡 Hint: Consider the definitions of both terms.
Question 2
Specific gravity is the ratio of soil solids density to the density of water. True or False?
- True
- False
💡 Hint: Think about how we define specific gravity in relation to water.
