Web4 nov. 2024 · Steps include: brainstorm, design, plan, create, improve. surface tension: A property of liquids in which water molecules are more attracted to each other than other molecules, causing the water to "stick together." surfactant: A substance that reduces the surface tension of a liquid in which it is dissolved.

WebWhat is surface tension. Surface tension is defined as the work, dW, required to expand a surface by dA. It is, thus, a direct measure of the energy needed to form a new surface of unit area, i.e. surface energy. Surface tension is a characteristic of any surface or interface, however, it is only directly measurable for liquids. Web14 mrt. 2024 · Liquids with low surface tension, however, have less of a difference between the tension on the surface and in the rest of the liquid. Pure water, for example, has significantly high surface tension. If you …

Webhydrogen bonding is only the reason intermolecular forces and surface tension are very strong for water.
