What are some examples of surface tension?

Answer 1

A dog running into the ocean

Answer 2

Some examples of surface tension are the spherical water drops on a flower, water in a tube where you notice the edge points (adjacent to inner tube surface) are at a level higher than the innermost water point level.

Water Skimmers

Pin/Paper clip floating in water

Lava Lamp

Answer 3

Have you ever seen water strider insects?

Well they can walk on top of the water's surface.

This is one example.

The force of the causes water to act if like an elastic film was covering the surface.

Answer 4

Surface tension is a phenomena arising due to the unbalanced force exerted on the liquid molecules present at the surface. Due to this various consequences take place like if we see in nature, then movement of fluids up to the top branches of tress is due to the capillary effect which is caused due to surface tension effects.

One other consequence is that some insects have the ability to walk on water. This is also due to surface tension effects.

Some other applications include using glycerin to remove oil stains. When glycerin is put on the oil or grease stains, the oil stain tend to gather inward due to surface tension and hence making it easier to remove.

Answer 5

Surface tension is a property of the surface of a liquid that allows it to resist an external force. It is revealed, for example, in floating of some objects on the surface of water, even though they are denser than water

Some Examples of Surface Tension

Let us see some more interesting effects of the surface tension in our daily life:

1) Dew drops: Have you noticed the drops of water on the leaves in your garden in the early morning? The moisture in the atmosphere condenses in the early morning and beads on the leaves due to surface tension. The surface tension gives spherical shape to water drops.

2) Beading of water on waxed car: Waxing changes the surface properties of your car. When the rains drops fall on your waxed car, they smoothly slide down to the ground keeping your car neat and clean and untouched. Water tends to adhere weekly to the wax and strongly to itself.

3) Formation of drops from liquid: When the liquid is stretched by applying force or it is poured on some surface it tends to form the droplets due to the surface tension the fluid.

4) Mercury used in the thermometer: The Mercury used in the thermometer does not stick to the wall of the capillary tube because of the surface tension. Had it stuck to the walls the measurement of temperature would not have been correct.

5) Separation of oil and water: The separation of oil and water is caused due to the difference in surface tension of the two liquids. There is also separation of the fuel and lubricating oil in the engine due to their surface tension. Had they mixed together, the fuel would have lost its combustion properties while lubricating oil would have lost its viscosity and lubrication properties.

6) Soap bubbles: Ordinarily the bubbles in water are unstable, but when surfactants are introduced in water its surface tension is reduced by factor of three or more. In such water the bubbles can remain stable; hence lots of bubbles are seen in such liquids.

Answer 6

Water striders walking on the surface of water, a needle floating on the surface of water, and water droplets forming a spherical shape on a surface are examples of surface tension in action.

Answer 7

when there is a penny and you are dropping droplets on the penny it causes surface tension

Answer 8

If you put a needle metal "fifteen with water that metal crime volume of heavy water is but a needle into the water that does not go to the attraction for surface water.
