What property of water allows water spider to walk across the surface of a pond?
In physics, surface tension is a force present within the surface layer of a liquid that causes the layer to behave as an elastic sheet. It is the force that supports insects that walk on water, for example.
An insect is able to walk across the surface of a pond without sinking because of the?
Insects are able to walk across bodies of water without sinking because of their weight. Insects weigh literally nothing.
What are the insects that use their skin to walk across thd surface of the stream?
Insects that are able to walk across the surface of water are called water striders. Water striders make use of the high surface tension of water together with their long, hydrophobic legs to stay above water.
Which mineral property is identified by the color of the powder left behind when it is rubbed across a surface?
streak
Why is an insect able to walk across the surface of a pond without sinking?
Insects that have the ability to walk on water have feet that are spread very far apart. This allows their weight to be distributed over a larger area and stops them from breaking the surface tension of water molecules sticking together.
Why is surface tension helpful to some oragisms?
Many insects and microscopic organisms need to be in direct contact with the air to feed, live, and reproduce. The surface tension on water allows many insects to "walk" across the surface making the capture of prey much easier. During the hatching cycle, many insects larvae come to the surface of the water, using the surface tension for support while releasing the larvae inside.
What happen to the needle when you added 2-3 drops of the detergent solution?
The needle floats on the tensioned surface of the water. When the detergent is added, the surface tension is broken and the needle sinks. Larva of mosquitoes hang from the surface to breath air. Pond-skaters can move across the surface, as can many aquatic insects. Detergent will also cause insects to sink.
What is an example of a sentence using the word skitter?
It amuses me to see the insects skitter across the surface of the pond.
What property of the structure of water allows water spiders to walk across the surface of a pond?
it is when water molecules in the water form a 'wall'.Pond skaters have legs that spread out away from their bodies, lowering the pressure exerted by their weight and not breaking the surface tension of the water
What happened to the needle when you added 2-3 drops of the detergent solution?
If you have floated a needle on the surface of the water in a glass then adding a little detergent will cause the needle to sink. This is because the presence of the detergent changes the surface tension of the water so that it can no longer support the needle.
Why is it easier to pull a box across a surface with an upward angle then push a box across a surface with a downward angle?
Push a box across a surface with a downward angle because gravity is helping.
Why can you pour a glass of water to the rim of the glass?
it's called "surface tension". It is the property of the surface of a liquid which causes it to behave like an elastic sheet. This is why a "water strider" insect can skate across the surface of a pond without sinking into the water. It is also what causes a drop of water - the surface tension of the water pulls it into a ball.
