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 epub download
Surface Tension of Water . The
surface tension of water is 72 dynes/cm at 25°C . It would take a force of 72 dynes to break a
surface film of water 1 cm long. The
surface tension of water decreases significantly with temperature as shown in the graph.

Surface tension is a phenomenon in which the
surface of a liquid, where the liquid is in contact with a gas, acts as a thin elastic sheet. This term is typically used only when the liquid
surface is in contact with gas (such as the air).
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. download Surface tension kindle download download Surface tension ePub
Surface tension definition is - the attractive force exerted upon the
surface molecules of a liquid by the molecules beneath that tends to draw the
surface molecules into the bulk of the liquid and makes the liquid assume the shape having the least
surface area.
Surface tension is a measure of the force acting at a boundary between two phases. If the boundary is between a liquid and a solid or between a liquid and a gas (air) the attractive forces are referred to as
surface tension, but the attractive forces between two immiscible liquids are referred to as interfacial
tension. Surface tension audiobook mp3
Surface tension is also viewed as the result of forces acting in the plane of the
surface and tending to minimize its area. On this basis,
surface tension is often expressed as an amount of force exerted in the
surface perpendicular to a line of unit length.

Surface tension. The work which is required to increase the size of the
surface of a phase is referred to as the
surface tension. As a measure of work per unit area or force per wetted length,
surface tension has the unit mN/m and is designated by the symbol σ (lower case sigma). ebook Surface tension buy cheap
Tjuven Surface Tension and Droplets:
Surface tension is responsible for the shape of liquid droplets. Although easily deformed, droplets of water tend to be pulled into a spherical shape by the cohesive forces of the
surface …
