ANSWER ASAP! Discuss the unique properties of water. (Polar, Hydrogen bonds, Cohesion, Adhesion)

Water has cohesive and adhesive properties.

Water molecules have strong cohesive forces due to their ability to form hydrogen bonds with one another. Cohesive forces are responsible for surface tension, the tendency of a liquid's surface to resist rupture when placed under tension or stress.

Adhesion and cohesion are important water properties that affects how water works everywhere, from plant leaves to your own body. ... Cohesion: Water is attracted to water, and Adhesion: Water is attracted to other substances.

Answer & Explanation:

The difference in electronegativity between oxygen and hydrogen atoms creates partial negative and positive charges, respectively, on the atoms.

Water molecules attract or are attracted to other polar molecules.

Molecules that do not dissolve in water are known as hydrophobic (water fearing) molecules.

Because of its extensive hydrogen bonding, water (H2O) is liquid over a far greater range of temperatures that would be expected for a molecule of its size. Water is also a good solvent for ionic compounds and many others because it readily forms hydrogen bonds with the solute.  

Cohesion holds hydrogen bonds together to create surface tension on water.

Since water is attracted to other molecules, adhesive forces pull the water toward other molecules.

Water is transported in plants through both cohesive and adhesive forces; these forces pull water and the dissolved minerals from the roots to the leaves and other parts of the plant.

Key Terms:

hydrogen bonds: A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

adhesion: The ability of a substance to stick to an unlike substance; attraction between unlike molecules

cohesion: Various intermolecular forces that hold solids and liquids together; attraction between like molecules

hydrophilic: having an affinity for water; able to absorb, or be wetted by water

hydrophobic: lacking an affinity for water; unable to absorb, or be wetted by water

polarity: The intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
