it is because a liquid is bounded by 3sides .thus it has only the upper free surface.

Why the needle of the iron swims on the water surface when kept gently?

It is due to the peculiar property of liquids called SURFACE tension. The free surface would act as if a stretched membrane.


what is the pull on the surface of liquids that allows liquids to form drop when they fall?

It is surface tension.


The pull on the surface of liquids that allow liquids to form drops when they fall are called?

The pull on the surface of liquids that allow liquids to form drops when they fall are called surface tension. This property is due to the cohesive forces between liquid molecules at the surface.

It is surface tension.


What is the difference between liquids with high surface tension and liquids with low surface tension?

Liquids with high surface tension have stronger forces between their molecules at the surface, causing them to form droplets and resist spreading. Liquids with low surface tension have weaker forces, allowing them to spread out more easily and wet surfaces.


When liquids are exposed air?

When liquids are exposed to air, they can evaporate due to the molecules in the liquid gaining enough energy to break free from the surface and enter the air as gas. This process is known as evaporation. The rate of evaporation can be influenced by factors such as temperature, surface area, and humidity.


Why does water pool or puddle on a flat surface instead of spreading out evenly?

surface tension is the result of cohesion which holds liquids together surface tension is the result of cohesion which holds liquids together surface tension is the result of cohesion which holds liquids together


Are there any surface liquids on titan or venus?

There are no liquids present on the surface of Venus. However, the appear to be lakes, seas, asn streams of liquid methane on the surface of Titan.


Does solids have surface?

Yes. Everything you can touch has a surface, even liquids


Does water have a low surface tension compared to other liquids?

Yes, water has a relatively high surface tension compared to other liquids.


What causes surface tension in liquids?

Surface tension in liquids is caused by the cohesive forces between the molecules at the surface of the liquid, which creates a "skin-like" layer that resists external forces.


How does the reduction of surface tension affect the behavior of liquids?

When surface tension decreases, liquids are less likely to form droplets and more likely to spread out. This can affect how liquids interact with surfaces and other substances.
