Question

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.

Answer 1

b. A small amount of water increases surface tension and holds the grain together Too much water between the grains wil eliminate suface fordion.

Step-by-step explanation:

The increase in cohesion between substances with the addition of a small amount of water is directly related to the increase in surface tension that water causes in this substance. However, with the exaggerated addition of water, superficial lust will not be able to be formed efficiently, or in any way, and therefore cohesion will be difficult.
