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
Why do water spiders float?
there is a thing called surface tension. Surface tention is the uneven forces acting on the particles on a surface of a liquid and this causes the water to act like a sort of thin film and therefor the spider can float.
What are three forces acting on a water glider when it is standing on a still pond?
One is "surface tension" which allows the spider to walk on water ; see related link .
What types forces does act on water tank?
These forces may be either external or internal. As Surface forces act on the surface of the water body by direct contact.
Which property of water allows insects to walk on water?
Certain insects (ones with a very light weight) are able to walk on water as their weight does not break the surface tension of the water. Water has a very high surface tension, therefore easily breaking and not supporting weight above a certain limit.
What type of spider can walk on water?
There is a genus of spiders called fishing spiders that can walk on water (a few of them can also swim in it as well using a portable silk bubble). They're known formally as Dolomedes. Fishing spiders have hairs on their legs that repel water, so that allows them to stand on the water. They eat frogs and other water-dwelling insects.
Can spiders really catch fish?
Yes.There is a genus of Australian spiders known as Fishing spiders (Dolomedes instabilis), of the family Pisauridaewhich, as their name suggest, catch fish, as well as tadpoles and frogs. These spiders have long, strong legs, and tend to rest by the edge of still ponds, with their legs touching the surface of the water. This suggests that these spiders can detect prey by touching the surface of the water: as prey approaches, the spiders will skim the surface of the water to catch creatures such as insects, small fish and tadpoles, and sometimes even submerge to catch them. They also lightly touch the water surface with their legs to lure fish closer.
What are the forces that holds water on the surface of the earth?
Gravity... I think
What property of water allows trees to suck up water?
Its "surface tension".
What is the difference between capillary action and surface tension?
surface tension is a product of cohesive forces (eg. water to water forces in a bubble) whereas capillary actionis a product of adhesive forces (eg. water climbing up a thin glass tube)
What property of water allows it to stick to a dry surface such as a wooden countertop?
Adhesion is what allows water to stick.
Which property of water allows small insects to walk on its surface?
Its mostly due to Surface Tensions, keeping them balanced on the water.
