A negatively charged chloride ion is surrounded by the partially positive charges of hydrogen atoms in water molecules. The cohesion of water molecules helps plants take up water at their roots. Cohesion of water molecules is also responsible for surface tension. For example, they allow nutrients to be transported to the top of a tree against the force of gravity. The thin tube is inserted into a cup of water, and the water climbs up in the tube, reaching a higher level than it does in the cup.

If this did not happen, plants and animals living in water would freeze in a block of ice and could not move freely, making life in cold temperatures difficult or impossible. The weight of a needle on top of water pulls the surface tension downward; at the same time, the surface tension of the water is pulling it up, suspending the needle on the surface of the water and keeping it from sinking. In principle, the oil yield is higher in the water-wet reservoirs whereas, in the oil-wet reservoirs additional, enhanced oil recovery methods are required to release the oil. Simple Diffusion, Osmosis, Facilitated Diffusion and Active transport. This formation happens to be less dense than its structure when it is in liquid form. just curious.
