Which best explains the surface tension of water? capillary action cohesion adhesion sublimation
The term that best explains the surface tension of water is “cohesion.”
Cohesion refers to the intermolecular attraction between molecules of the same substance, and it is responsible for the formation of surface tension.
In the case of water, the oxygen atoms in the water molecule have a slight negative charge, while the hydrogen atoms have a slight positive charge.
This causes the water molecules to be attracted to each other, resulting in a strong cohesive force.
H2O has strongest intermolecular forces because this molecules make hydrogen bonding.
Hydrogen bonding are created if hydrogen are bound with oxygen, nitrogen, and fluorine. If any molecules held together by hydrogen bonding due to this, it make strongest type of intermolecular forces. Such as, dipole dipole hydrogen bond.
So, h2O has strongest type intermolecular forces such as, dipole dipole hydrogen bond.
Surface tension is the result of the cohesive forces between water molecules at the surface of the water.
The surface molecules experience a net inward force because they have fewer neighboring molecules to bond with than the molecules below them, which are surrounded by other water molecules.
This results in the formation of a “skin” or surface layer on the top of the water that can resist external forces, like the weight of an object placed on it or the force of wind blowing over it.
Capillary Action Cohesion Adhesion Sublimation
Capillary action refers to the ability of a liquid to flow through narrow spaces or tubes without the assistance of, or in opposition to, external forces like gravity.
This is due to the interplay between cohesive forces, which cause the molecules within the liquid to stick together, and adhesive forces, which cause the liquid to adhere to the surface of the tube or narrow space.
Capillary action is responsible for phenomena such as the ability of a paper towel to absorb water, and the rise of water through plant roots.
Cohesion refers to the attraction between molecules of the same substance. In the case of a liquid, this means that the molecules within the liquid are attracted to each other, creating a cohesive force that holds the liquid together.
Cohesion is responsible for the surface tension of liquids, which allows insects to walk on water, and for the ability of some liquids, such as mercury, to form into droplets.
Adhesion refers to the attraction between molecules of different substances.
In the case of a liquid, this means that the liquid molecules are attracted to the surface of another material, such as a solid surface or the surface of a tube.
Adhesion is responsible for phenomena such as capillary action, in which a liquid is drawn up into a narrow space or tube due to its attraction to the surface of that space.
Sublimation refers to the process by which a solid transitions directly into a gas without passing through the liquid phase.
This occurs when the vapor pressure of the solid exceeds the atmospheric pressure around it, causing the solid to evaporate directly into a gas.
Examples of substances that undergo sublimation include dry ice (solid carbon dioxide) and mothballs (solid naphthalene).
