cWhat is the difference between adhesion and cohesion?
a. Adhesion is the tendency of water molecules to stick to each other while cohesion is the
tendency of water molecules to stick to other solids.
b. Adhesion allows water to create a surface tension while cohesion causes capillary action.
c. Adhesion is the tendency of water molecules to stick to solids while cohesion is the
property that allows water molecules to stick to each other.
d. Adhesion and cohesion are synonymous terms.
ANS: C
Cohesion is the ability of water molecules to stick to each other. This property allows water to create a
skin of sorts or surface tension. Adhesion is water's tendency to attach to solids which causes capillary
actions. Information can be found in the section The Water Molecule Is Held Together by Chemical
Bonds.
