What is the main source of water on earth?
The main source of water on earth is the ocean. Although it is salty, it makes up almost 97% of the world's water.
Where can i find aquifers?
Aquifers can be found underground in many places around the world. They are typically located beneath the Earth's surface where water is stored in permeable rock or sediment layers. Aquifers can be accessed through wells for drinking water and irrigation purposes.
If you toss a rock into a lake what happens to the rock as it sinks?
As the rock sinks in the lake, it displaces water, causing a disturbance in the water's surface. The rock experiences a buoyant force pushing against it as it sinks due to the displaced water. Eventually, the rock settles at the bottom of the lake due to gravity.
What did earth's surface look like then during the devonian period?
Pangea finished forming during the Permian Period so there was only one landmass. It gradually became more arid and the south was very cold and much was under an ice pack. The period ended with over 90 percent of marine life and 70 percent of land animals extinct.
What were wells used for at ancient times?
Wells in ancient times were primarily used as a reliable water source for drinking, irrigation, and domestic use. They also played a crucial role in sustaining communities and enabling agricultural activities in areas where surface water was scarce. Additionally, wells often had symbolic and ritualistic significance in various cultures.
Why did heating the water affect the surface tension?
Surface tension is lower at higher temperatures.
How would you expect the surface tension of water to be affected by increasing temperature?
surface tension of water is affected by temperature as it starts to evaporate when there is hot temperature but due to unnatural medium its surface starts to freeze when the temperature outside is cold,so this gives the reason that surface tension of water is affected by temperature.
What is the effect of sodium chloride on the surface tension of water?
The surface tension of water is increased for salted water.Sodium chloride increase the surface tension of water.
What makes a needle to float in water?
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.
Can you explain the soap and pepper experiment and its significance in demonstrating surface tension?
The soap and pepper experiment demonstrates surface tension by showing how soap disrupts the surface tension of water. When pepper is sprinkled on water, it floats due to surface tension. Adding soap breaks the surface tension, causing the pepper to move away from the soap. This experiment helps illustrate how surface tension works and how it can be affected by different substances.
What property of water let's bugs walk on water?
surface tension
Does salty water have a meniscus?
Yes, but it might be slightly different because the salt upsets the water's surface tension.
How does surface tension of water compare with the surface tension of most other liquid?
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.
Does water have the highest surface tension?
No, mercury has a higher surface tension.
What is the tightness across the surface of water is called?
Surface tension is the tightness across the surface of water caused by the attraction between water molecules.
How do the word use surface tension?
A water skipper is able to walk on water based on surface tension.
Does density of water increase or decrease the surface tension of water?
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.
