Why does water have a greater degree of surface tension than most other liquids?

Water molecules stick to each other because they can form what are called hydrogen bonds. The positively charged hydrogen atoms are attracted to the negatively charged oxygen atoms of other molecules. This stickiness means that a water molecule wants to be next to as many other water molecules as possible. so if you put something light on the surface of water, it might not be heavy enough to force the water molecules underneath it to separate.

What is water's surface tension?
Here are some explanations of surface tension:Surface tension is a property of the surface of a liquid that causes it to behave as an elastic sheet. It allows insects, such as the water strider (pond skater, UK), to walk on water too. It allows small objects, even metal ones such as needles, razor blades, or foil fragments, to float on the surface of water, and it is the cause of capillary action.5.18 pounds / feet at 0 degree Celsius. Or as I remember it is 72 dyne / centimeter at 25 degree Celsius. The surface tension of water is the force required in order to float at the water's surface, hence making water to behave like an elastic sheet.Water surface tension is contractive tendency of the surface of a liquid that allows it to resist an external force. The beading of water on a waxy surface, such as a leaf, is an example of water surface tension.
What determines the amount of friction?
The roughness of the two objects coming in contact determines the degree of friction.
Rank the sizes of one degree in each scale from largest to smallest of temperature?
1 degree Centigrad = 1 degree Kelvin = 1.8 Degree F = 1.8 degree R
What is 20 degree Celsius in farihight?
20 degree Celsius = 68 degree Fahrenheit
What is a PS degree?
A PS degree is the abbreviation for a psychology degree. Some common psychology degree's are: PhD, PsyD, MS, MA, EdD.
Rank these liquids by their expected surface tension?
Mercury is the liquid with the strongest surface tension.
How is surface tension important in nature?
There are technological examples of the importance of surface tension. The degree to which a liquid wets a surface or forms beads depends in large part on the surface tension. Obviously, one wants one's raincoat to bead water as well as the wax on one's car. But the opposite is true for a lubricant. One wants oil to adhere to a surface of a bearing. Coatings are designed with wettabilty as a primary consideration. Cloth may be treated with materials to prevent wetting, but that is also an example where the surface texture or roughness plays a critical role. Paint is an example of a coating that would be carefully evaluated for wettability depending on the application. Surface tension of water is obviously a property of the surface and the surface of water is an interface, i.e. the place where water comes in contact with anything else. Surface tension is really a measure of how much energy is require to create a surface of a liquid. (Liquids would rather not have much surface, that is why they form drops - to minimize the surface.) The surface tension of water is large and that surface tension determines many of the properties of any interface with water and changing the surface tension changes those properties. A lot of biology happens at the interface of one compartment of water and another and the entire reason we can even have living cells is a result of the large surface tension that stabilizes a cell membrane. Finally, all those little bugs which walk around on the top of water would have no where to live without water tension.
What causes the high surface tension and low vapor pressure of water?
Hydrogen bonding causes the inward force that minimizes the surface area of water, and the tendency of water molecules escaping this bond to become vapor is slim and/or slow, thus creating it's low pressure.

Is the tower bridge tension or compresion?
Arch bridges are always under compression. The force of compression is pushed outward along the curve of the arch toward the abutments.The natural curve of the arch and its ability to dissipate the force outward greatly reduces the effects of tension on the underside of the arch. The greater the degree of curvature (the larger the semicircle of the arch), however, the greater the effects of tension on the underside.Therefore, if the arch is a perfect circle, the tension is negligible.
How much can the surface of tension of water hold?
Pure water can roughly hold 0.073 grams per cm at 20 degree Celsius.Impurities can change the figures.
The slope of the mold release?
The appropriate release slope can avoid the product pulling hair (pulling flowers). Smooth surface of the mold slope should be ≥ 0.5 degrees, fine grain (sand surface) surface is greater than 1 degree, coarse grain surface is greater than 1.5 degrees.
How much weight can the surface tension of water hold?
Pure water can roughly hold 0.073 grams per cm at 20 degree Celsius.Impurities can change the figures.
What is a zymometer?
A zymosimeter (or zymometer) is an instrument for ascertaining the degree of fermentation occasioned by the mixture of different liquids, and the degree of heat which they acquire in fermentation.

Why is one degree Celsius greater then one degree Fahrenheit?
five
