Synopsis This project report explains about the surface tension and capillarity of liquid through a simple experiment of finding the capillarity of various detergents. Oil stains and grease on dirty clothes cannot be removed‚ using water alone‚ because water does not wet them. If detergents added ‚ surface tension is decreased‚ the area of contact is increased. Detergent molecules have the shape of a hairpin‚ one of which is attracted to water

Surface Tension My problem was to find out how to test or measure surface tension. I think the reason of some of the force in surface tension is cohesion and gravity. Surface Tension is the condition existing at the free surface of a liquid‚ resembling the properties of an elastic skin under tension. The tension is the result of intermolecular forces exerting an unbalanced inward pull on the individual surface molecules; this is reflected in the considerable curvature at those edges where the

Term Report Microsoft Surface Table Acknowledgements We would like to express our deepest appreciation for our professor‚ Dr. Michael Kamins. It would have been practically impossible for us to pursue this project without his invaluable advice and guidance. We would also like to thank our classmates for encouraging us during our presentation and providing great advice to improve our project. We would also like to thank the Stony Brook College of Business for allowing us to use the

such as methane‚ however‚ have weak cohesion due only to Van der Waals forces that operate by induced polarity in non-polar molecules. Cohesion‚ along with adhesion (attraction between unlike molecules)‚ helps explain phenomena such as meniscus‚ surface tension and capillary action. Mercury in a glass flask is a good example of the effects of the ratio between cohesive and adhesive forces. Because of its high cohesion and low adhesion to the glass‚ mercury does not spread out to cover the bottom

am investigating the relationship between surface area and the volume of a model cactus and to determine whether this relationship affects the loss of water. We used oasis blocks‚ an absorbant material used by florists as a substitute for a cactus‚ that would soak up the water‚ and thus ideally show the percentage water loss by weighing the before and after evaporation weights. Independent Variable The independent variable is the total surface area for each size of the blocks and I think this

equilibrium”‚ whatever the temperature may be. The larger the surface area‚ means there can be more “paths” from the sides of the body that are capable of releasing this heat particles‚ and reaching thermal equilibrium faster. This is what happens when a hotter body is subjected to a colder one. Research Question: How does the surface area to volume ratio affect heat loss in organisms? Hypothesis: I hypothesize that the larger the surface area to volume ratio‚ the more heat will be lost and vice

In mathematics‚ the Klein bottle ([klaɪ̯n]) is a non-orientable surface‚ informally‚ a surface (a two-dimensional manifold) with no identifiable "inner" and "outer" sides. Other related non-orientable objects include the Möbius strip and the real projective plane. Whereas a Möbius strip is a two-dimensional surface with boundary‚ a Klein bottle has no boundary. (For comparison‚ a sphere is an orientable surface with no boundary.) The Klein bottle was first described in 1882 by the German mathematician

CU2641 - Undertake agreed pressure area care Describe the anatomy and physiology of the skin in relation to skin breakdown and the development of pressure sores Skin is the largest organ of the body‚ covering and protecting the entire surface of the body. The total surface area of skin is around 3000 sq inches or roughly around 19‚355 sq cm depending on age‚ height‚ and body size. The skin‚ along with its derivatives‚ nails‚ hair‚ sweat glands‚ and sebaceous glands forms the integumentary system

Investigating the effect of surface area to volume ratio on Osmosis As far as living organisms are concerned‚ they are all made up of cells whereas‚ the membrane surrounds all those cells. The cell membrane has the key responsibility to maintain a stable interval environment. Even though‚ Cell membrane is made up of phospholipids bilayer and has that great amount flexibility making it unbreakable while transportation of substances. However‚ certain substances such as‚ dissolved gases‚ sugars‚ salt
