Adding a small amount of water to a substance increase its cohesion; whereas, adding a lot of water decreases its cohesion. Why? a. A small amount of water will precipitate cement into the pores of the material, whereas too much water will not allow that coment to form.
b. A small amount of water increases surface tension and holds the grain together Too much water between the grains wil eliminate suface fordion.
c. Water has a small electrostatic force that disrupts the gravitational attraction of the grans and forces them to move away from each other.
d. A small amount of water decreases surface tension, allowing the grains to bond together, whereas too much water will increase surface tension and force the grains away from each other.
