Does water have a relatively high or low surface tension?
MERCURY has a higher surface tension than water. This highest surface tension between liquids is 487 mN/m at 15 0C.
What does high surface tension cause water to do?
High surface tension causes water to behave as if its surface had an elastic membrane, which was stretched. Due to water's high surface tension, effects like tears of wine and rain water beading on a leaf or grass happen.
What happens when the high surface tension of water?
Surface tension is the amount of attraction the surface of an object has.Surface tension is easily demonstrated by observing a pool of water. Put your finger in the water and slowly... i mean "slowly"... pull your finger away and you will see the water is actually attracted to your finger and the water will stay on your finger as you pull your finger off the pool of water. This is because of surface tension.Viscosity is the resistance of a liquid flow. A high viscosity means the liquid is thicker and does not move as readily. (And technically solids have an infinite viscosity because they do not "flow").A high viscous liquid would be like syrup.A low viscous liquid would be like water.Now... a high viscous liquid (like syrup) has a higher surface tension than a low viscous liquid. Do the "finger" demonstration with syrup. You will notice that syrup (being more viscous) will actually be attracted to your finger more than water is. Once you put your finger in a pool of syrup and bring it out... more syrup will be still on your finger.If you relate the water and syrup demonstration you will see that a higher viscosity means a greater surface tension and a lower viscosity means a lower surface tension.
Why does low-surface-tension-liquids-clean-better than high-surface-tension-liquids?
Low surface tension means high wetting as it represents low contact angle. It is therefore very easy for a low surface tension water / liquid to wet the surface ( usually solid) and get rid of the dirty in a same way a surfactant does unlike a high surface tension liquid which can't wett the surface containing the dirty....

Does the pH of water remain exactly neutral because of the high surface tension of water?
The pH of water is not related to surface tension.
Does water have a relatively high or low surface tension?
MERCURY has a higher surface tension than water. This highest surface tension between liquids is 487 mN/m at 15 0C.
What liquid have the strongest surface tension?
Mercury is the liquid with the strongest surface tension.
Water sticks to the finger but Mercury does not. why?
Mercury has a high surface tension. NB Don't try it yourself, mercury is very poisonous.
Does water have the highest surface tension?
No, mercury has a higher surface tension.
Does water or Mercury have greater surface tension?
mercury
What substance has the largest surface tension at room temperature?
The highest surface tension at 15 0C is the surface tension of mercury: 487 dyn/cm.
Why are mercury drops spherical?
Mercury has a very high surface tension and does not easily wet most other surfaces. For a given amount of mercury, a sphere has the smallest possible ratio of surface area to volume and is therefor the lowest energy shape for the mercury.
Mercury has its meniscus upward?
due to surface tension
What does high surface tension cause water to do?
High surface tension causes water to behave as if its surface had an elastic membrane, which was stretched. Due to water's high surface tension, effects like tears of wine and rain water beading on a leaf or grass happen.
What is the reason the high surface tension of water?
The reason behind the high surface tension of water is hydrogen bonds. This very strong bond enables small insects to walk on the surface of water.
