Hydrogen Bonding •Attraction between hydrogen atoms who are bonded to strongly electronegative atoms like O, F, or Cl and another polar molecule. All rights reserved. 1994). Surface tension definition lets us know that the surface tension mainly depends upon the forces of attraction between the particles within the given liquid and also upon the gas, solid, or liquid in contact with it.. The 250 kg cylinder shown in the figure below is...

What is the relationship... What is Viscosity? A property of liquids such that their surfaces behave like a thin, elastic film.
It can equally be defined as the energy required to increase the surface area by one square metre, i.e. Published by Houghton Mifflin Harcourt Publishing Company. A property of liquids arising from unbalanced molecular cohesive forces at or near the surface, as a result of which the surface tends to contract and exhibit properties resembling those of a stretched elastic membrane. Because of surface tension, the surface of a liquid can support light objects (such as water beetles on the surface of a pond).

Imagine a water strider bug that is supported on... 1. It is measured in newtons per metre. a property of liquids caused by intermolecular forces near the surface leading to the apparent presence of a surface film and to capillarity, etc, a measure of this property expressed as the force acting normal to one side of a line of unit length on the surface: measured in newtons per metre. Surface tension is an effect of intermolecular attraction, in which molecules at or near the surface undergo a net attraction to the rest of the fluid, while molecules not near the surface are attracted to other molecules equally in all directions and undergo no net attraction.

Create your account. Surface tension The expression of intermolecular attraction at the surface of a liquid, in contact with air or another gas, a solid, or another immiscible liquid, tending to pull the molecules of the liquid inward from the surface; dimensional formula: mt-2.
The force exerted along the surface of a fluid that causes it to “bead up” and form into drops. - Definition, Equation & Units, Hydrostatic Pressure: Definition, Equation, and Calculations, Real Gases: Using the Van der Waals Equation, Human Anatomy & Physiology: Help and Review, UExcel Anatomy & Physiology: Study Guide & Test Prep, Environmental Science 101: Environment and Humanity, UExcel Earth Science: Study Guide & Test Prep, Prentice Hall Biology: Online Textbook Help, Holt McDougal Modern Biology: Online Textbook Help, Biological and Biomedical
