Cohesive forces between liquid molecules on the surface cause a phenomenon known as surface tension. Due to the lack of surrounding molecules, surface molecules adhere more strongly to another than they would inside a liquid. Surface tension is measured in newtons per meter (N/m) or dyne per centimeter (dyn/cm). The formula to figure surface tension is gamma equals the ratio of the surface force to the distance along which the force acts or gamma = F / d. Variables such as temperature and solution purity can cause F to vary. Pure water at 20 degrees (C) has a surface tension of 72.8 dynes/cm.
The surface tension of water is increased for salted water.Sodium chloride increase the surface tension of water.
surface tension
yes
Tension does not have anything to do with evaporation.
The surface tension of water is higher than that of most other liquids. Water has a surface tension of 7.29 * 10-2 J/m2 at 20oC.
A needle can float on water due to surface tension. When the needle is carefully placed on the surface of the water, its weight is not enough to break the surface tension created by the water molecules, causing it to float.
The surface tension of water is due to cohesive forces between water molecules. Density does not directly affect surface tension, but impurities or additives can alter it. Essentially, the surface tension of water remains constant regardless of its density.
A water skipper is able to walk on water based on surface tension.
No, mercury has a higher surface tension.
Yes, water temperature can affect surface tension on a penny. As water temperature increases, surface tension generally decreases. This means that with higher water temperature, the water is less likely to bead up and more likely to spread out on the penny, reducing the surface tension.
It weakens the surface tension of water allowing us to blow BUBBLES!! :D
