List 3 basic liquids that do not wet a glass?
Mercury: Due to its high surface tension, mercury does not wet glass and forms droplets on its surface. Carbon tetrachloride: This liquid has low surface tension, which causes it to bead up on glass rather than spread out. Liquid bromine: Like mercury, liquid bromine does not wet glass due to its high surface tension property.
Does water have a relatively high or low surface tension?
Water has a relatively high surface tension compared to other liquids due to its strong hydrogen bonding properties between water molecules. This results in the formation of a cohesive layer at the surface of water, allowing it to resist external forces and form droplets.
What does Mercury stick to?
Mercury has a strong affinity for certain metals, such as gold, silver, and aluminum. This property allows it to form alloys, called amalgams, with these metals. Additionally, Mercury forms a slight meniscus at the edge of solid surfaces due to its high surface tension.
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....

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 liquid have the strongest surface tension?
Mercury is the liquid with the strongest surface tension.
What is the significance of surface tension of mercury in relation to its unique properties and behavior?
The surface tension of mercury is significant because it is much higher than that of other liquids, making it behave uniquely. This high surface tension allows mercury to form spherical droplets and flow smoothly, even against gravity. This property contributes to its use in thermometers and barometers.
Which has greater surface tension of CH4 H2O H2S and Hg?
Among the given substances, Hg (mercury) has the greatest surface tension due to its strong intermolecular forces and cohesive properties. Mercury's atoms are closely packed, which leads to high surface tension compared to methane (CH4), water (H2O), and hydrogen sulfide (H2S).
Does water have a relatively high or low surface tension?
Water has a relatively high surface tension compared to other liquids due to its strong hydrogen bonding properties between water molecules. This results in the formation of a cohesive layer at the surface of water, allowing it to resist external forces and form droplets.
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.
What substance has the largest surface tension at room temperature?
Water has the highest surface tension of common liquids at room temperature. This is due to its strong hydrogen bonding, which creates cohesive forces between water molecules that pull them together and give water its high surface tension.
Rank these liquids by their expected surface tension?
Mercury is the liquid with the strongest surface tension.
Mercury has its meniscus upward?
If the meniscus of mercury in a glass tube is curved upwards, it indicates that the adhesive forces between mercury and the glass are stronger than the cohesive forces within the mercury. This is due to the high cohesion and adhesive properties of mercury.
