1. Volume Relations

Try these first

1. 1.

   What is the formula for void ratio?

   Hint

   Think of the relationship between void volume and soil solids.

2. 2.

   Define porosity.

   Hint

   Remember the term 'percentage' when describing porosity.

3. 3.

   What is the formula for calculating the void ratio?

   • V_v / V_s
   • V_s / V_v
   • V_t / V_v

   Hint

   Think about what voids refer to.

4. 4.

   True or False: Higher porosity indicates less void space in soil.

   • True
   • False

   Hint

   Remember the definition of porosity.

5. 5.

   Calculate the void ratio and porosity for a soil sample with a total volume of 100 liters, of which 30 liters is solid and 70 liters is void.

   Hint

   Use the definitions for your calculations to get the answers.

6. 6.

   Discuss how changing the degree of saturation affects the engineering properties of soil, with examples.

   Hint

   Analyze how moisture influences soil behavior.
