What is a real life example of surface tension?
Walking on water: Small insects such as the water strider can walk on water because their weight is not enough to penetrate the surface. Floating a needle: A carefully placed small needle can be made to float on the surface of water even though it is several times as dense as water.
Where can you find the application of surface tension in daily life?
Examples of Surface Tension
- A Drop of Liquid.
- Soaps and Detergents.
- Washing with Hot Water.
- Clinical Test for Jaundice.
- Water Striders.
- Capillary Action.
- Formation of a Meniscus.
- Bubbles.
What is the role of surface tension in daily life?
The effects of surface tension are of central importance in many everyday phenomena: it causes small droplets of rain to stick to your windows, creates bubbles when you add detergent in your sink, and propels water-striding insects on the surface of ponds.
How do living things use surface tension?
. surface tension of water helps creatures(mostly of insecta class such as water striders) to walk on water. . it also helps water to move up the xylem tissue of higher plants without breaking up.
Which animals use surface tension?
Insects, such as water striders, and spiders, such as fisher spiders, can glide or scamper across the surface of water. These critters are small enough that their weight can be supported almost entirely by surface tension, the relatively weak forces that hold water molecules together.

Where is surface tension found in everyday life?
Surface Tension in Everyday life. wax secreted on the insect’s legs combined with surface tension Surface tension is everywhere, from early morning dew to tent covers. Here are some examples that are in everyday life
Which is the best example of surface tension?
Examples of Surface Tension. Drops of water. When using a water dropper, the water does not flow in a continuous stream, but rather in a series of drops. The shape of the drops is caused by the surface tension of the water.
What is the surface tension of water at 25°C?
The surface tension of water is 72 dynes/cm at 25°C . It would take a force of 72 dynes to break a surface film of water 1 cm long. The surface tension of water decreases significantly with temperature as shown in the graph.
When does the tension of the interface occur?
Surface tension occurs during a gas-liquid interface, but if that interface comes in contact with a solid surface – such as the walls of a container – the interface usually curves up or down near that surface. Such a concave or convex surface shape is known as a meniscus The contact angle, theta, is determined as shown in the picture to the right.
