PPT-Surface Tension CER Notebook Set-Up

Do Now SWBAT analyze how surface tension effects the amount of drops a penny can hold by writing a claim evidence reasoning statement Watch the video and answer these questions 1 What do the scientists want . Large organic compounds which are responsible for catalyzing biochemical reactions, as well as providing . structure, mobility, . and . function . for cells.. What is surface tension?. Have you ever seen one of these insects? The . Below surface, forces act equal in all directions. At surface, some forces are missing, pulls molecules down and together, like membrane exerting . tension. on the . surface. Pressure increase is balanced by surface tension, . Properties of Water. Lesson 1. The Big Idea of this Investigation. Water, which covers most of Earth's surface is the only substance on Earth that is found naturally in all three states of matter. Water can change from one state to another depending on the amount of heat that is added or taken away from it.. Fluid Bridge. 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. (High voltages must only be used under appropriate supervision - check local rules.). Basics of adsorptive therapy . “Yesterday, I couldn’t define colloid chemistry; today, I’m doing it. .”. From Abbott’s Flatland. Colloidal Chemistry. A colloid is a substance microscopically dispersed evenly throughout another . Review -- Muscle Elastic and Active Forces. Static Measurement of Compliance Curves. The Compliance of an Air-Filled Lung. The Compliance of a Saline-Filled Lung. Tissue Elastance in the Lung. Compliance of the Lung In Different Disease States. structure, mobility, . and . function . for cells.. 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).. interface normal essentially assumes equivalent variable) not take solutions. However, is clear and the and the are both boundary condition, between theoretical could be seriously affected experimenta Lecture . – 4. Dr.Zahoor Ali Shaikh. 1. Elastic Behavior Of The Lungs. Elastic Behavior of the lungs is due to elastic connective tissue and alveolar surface tension.. During Inspiration – lungs expand.. Surface Tension. Done. by:. Assist. . . Lec. . . Sura. . Zuhair.

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 (J/m. 2. ). You can also think of it as a. Fundamentals of adsorption therapy. Chromatography. Surface energy and surface tension. Living organism is a set of systems with highly developed interface - skin, blood vessel walls, cell membranes. 26.6.12. Surface Tension. Temperature. Solute. Solutes can have different effects on surface tension depending on their structure:. Little or no effect, for example sugar. Increase surface tension, inorganic salts. At surface, some forces are missing, pulls molecules down and together, like membrane exerting . tension. on the . surface. Pressure increase is balanced by surface tension, . s. . surface tension = magnitude of tension/length.
