Surface Tension Definition in Chemistry ThoughtCo

May 07, 2019· Surface Tension Definition . Surface tension is a physical property equal to the amount of force per unit area necessary to expand the surface of a liquid.. It is the tendency of a fluid surface to occupy the smallest possible surface area. Surface tension is a principal factor in capillary action.. The addition of substances called surfactants can reduce the surface tension of a liquid.

Surface Tension Introduction to Chemistry

Units of Surface Tension. Surface tension is expressed in units of force per unit length or of energy per unit area (for instance, N/m or J/m 2). The two are equivalent, but when referring to energy per unit area, people use the term “surface energy,” which is a more general term in the sense that it applies to solids as well as to liquids.

surface tension Definition, Examples, & Facts Britannica

Surface tension depends mainly 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 molecules in a drop of water, for example, attract each other weakly. Water molecules well inside the drop may be thought of as being attracted equally in all directions by the surrounding molecules.

Surface Tension Chemistry LibreTexts

Aug 15, 2020· Surface tension is the energy, or work, required to increase the surface area of a liquid due to intermolecular forces. Since these intermolecular forces vary depending on the nature of the liquid (e.g. water vs. gasoline) or solutes in the liquid (e.g. surfactants like detergent), each solution exhibits differing surface tension properties.

Surface Tension Purdue Chemistry

Surface Tension. Surface tension is measured as the energy required to increase the surface area of a liquid by a unit of area. The surface tension of a liquid results from an imbalance of intermolecular attractive forces, the cohesive forces between molecules: . A molecule in the bulk liquid experiences cohesive forces with other molecules in all directions.

Surface Tension Chemistry, Class 11, States of Matter

May 03, 2020· Surface tension is a property of liquid which arises due to the fact that the molecules of the liquid at the surface are in different situation than those in the interior of the liquid. A molecule lying inside the liquid is surrounded by other molecules and so is

Surface tension (video) Chemistry of life Khan Academy

Feb 18, 2016· And you have probably observed surface tension many, many, many times in your life in the form of, say, a water droplet. A water droplet, it's able to have this roughly round shape because all the little water molecules on the surface of the water droplet, and here the surface might even be on the

Viscosity & Surface Tension Definition With Examples Of

Surface tension is the amount of energy required to increase the surface of the liquid by unit area. In other words, it is also the property of the liquid surface that resists force. Intuitively, it keeps a barrier between foreign materials and liquid as well as this is the force that holds the

What is surface tension in chemistry? Quora

Oct 07, 2018· Hello! Surface tension is a physical property equal to the amount of force per unit area necessary to expand the surface of a liquid. It is the tendency of a fluid surface to occupy the smallest possible surface area. Surface tension is a principa...

Surface Tension and Water

Jun 28, 2019· Surface tension disinfectants: Disinfectants are usually solutions of low surface tension. This allow them to spread out on the cell walls of bacteria and disrupt them. Soaps and detergents: These help the cleaning of clothes by lowering the surface tension of the water so that it more readily soaks into pores and soiled areas.

Surface Tension Purdue Chemistry

Surface Tension. Surface tension is measured as the energy required to increase the surface area of a liquid by a unit of area. The surface tension of a liquid results from an imbalance of intermolecular

Surface Tension Chemistry for Non-Majors

The surface tension of a liquid is a measure of the elastic force in the liquid’s surface. Liquids that have strong intermolecular forces, like the hydrogen bonding in water, exhibit the greatest surface tension.

11.4: Intermolecular Forces in Action- Surface Tension

Aug 14, 2020· Surface tension is the energy required to increase the surface area of a liquid by a unit amount and varies greatly from liquid to liquid based on the nature of the intermolecular forces, e.g., water with hydrogen bonds has a surface tension of 7.29 x 10-2 J/m 2 (at 20°C), while mercury with metallic bonds has as surface tension

Surface Tension Formula Definition, Equations, Examples

Surface tension is the attractive force found in liquids which is responsible for pulling surface molecules in the rest of the liquid. Further, it minimizes the surface area. The attractive forces we are talking

Surface Tension Middle School Chemistry

The water molecules at the surface are attracted to the charged end of the detergent molecules. As the surface water molecules are attracted outward, this acts against their inward attraction that was creating the surface tension. This reduces the surface tension

What is surface tension in chemistry? Quora

Oct 07, 2018· Hello! Surface tension is a physical property equal to the amount of force per unit area necessary to expand the surface of a liquid. It is the tendency of a fluid surface to occupy the smallest possible surface area. Surface tension

The Meaning of Surface Tension and its Practical

The Meaning of Surface Tension and its Practical Applications. Surface tension is a physical phenomenon that we observe in our daily life. Raindrops take a spherical shape. 'tears of wine' are seen in a glass on pouring an alcoholic beverage in it, formation of spherical soap bubbles all these are examples of surface tension.
