Water content is given by:

• Weight of water/mass of soil

• Mass of water/mass of solid

• Mass of water/mass of soil

• Mass of water/weight of solid

Fine particles are those particles with size less than _______ mm diameter.

• 0.023

• 0.09

• 0.075

• 4.75

The mass density of water at 4⁰C is:
