Hydrophobic phenomena in the natural world have inspired inventions in the fields of materials science and nanotechnology. Identify a product that uses hydrophobic technology, and specify the problem or need that it solves. What claims have been made about the product’s effectiveness? Explain how you could scientifically test the validity of such claims and how the data generated from your procedure would be used.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
