1.1 Structure of Water and Hydrogen Bonding

Cohesion

when two molecules that are same forming hydrogen bond (example: raindrops)

Adhesion

when two molecules are different forming hydrogen bonds (example: water sticking on window)

Hydrogen Bonds

A weak attraction between a highly electronegative atom and hydrogen atom

Surface Tension

water uses hydrogen bonds to hold objects dense than itself (can use cohesion or adhesion) allowing them to remain on the surface (example bug walk on water without sinking)

Capillary Action

to move up narrow spaces against gravity due to the combined forces of by both cohesion and adhesion (example water moving up plant stem)
