Water has both cohesive and adhesive forces that are relatively strong. That is, its molecules are strongly attracted to one another and to many other kinds of molecules. What kind of bond forms between two different water molecules?
|
|
compound bond
|
|
|
double bond
|
|
|
hydrogen bond
|
|
|
ionic bond
|
Explanation:
Detailed explanation-1: -Adhesion vs Cohesion In water, this behavior is due to the hydrogen bonding of the molecules. Water has two positive poles, at the hydrogen atoms, and one negative pole, at the oxygen atom.
Detailed explanation-2: -Water does not wet waxed surfaces because the cohesive forces within the drops are stronger than the adhesive forces between the drops and the wax. Water wets glass and spreads out on it because the adhesive forces between the liquid and the glass are stronger than the cohesive forces within the water.
