PPT-Determination of surface tension of a liquid

1 Surface tension is defined as the amount of energy required to increase the surface area of a liquid by a unit amount So the units can be expressed in joules per square meter Jm 2 You can also think of it as a.

If a high voltage is applied to a fluid (e.g. . deionized. water) in two beakers, which are in contact, a fluid bridge may be formed. Investigate the phenomenon.

What is surface tension?. Have you ever seen one of these insects? The . Gerridae. family (or Water Strider) takes advantage of surface tension.. Intermolecular forces between the molecules in the bulk experience equal pull on all sides, resulting in a net force of zero. However, molecules at the surface (or interface) experience a significantly greater “pull” from the molecules below them in the liquid than from the gas molecules above them. The net force results in a “pull” towards the bulk liquid (known as surface tension).. Radionuclide Transfer. Transfer Considerations. STOP. RadionuclideTransfer. Once the radionuclide is produced, it is necessary to get it from the cyclotron to the chemistry laboratory. If the radionuclide is in the form of a gas, the transfer can usually be done with pressure and perhaps a push gas. Surface Tension. Done. by:. Assist. . . Lec. . . Sura. . Zuhair. Assist. . .
