[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
|
|
The insects are light enough so that they do not break the hydrogen bonds holding the water molecules together
|
|
|
The insects actually use their wings to hover slightly above the water’s surface and they only skim it with their feet
|
|
|
The insects’ feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water’s surface
|
|
|
The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next
|
Detailed explanation-1: -Their feet push the surface of the water down slightly, but they do not break the surface. Why? The insects actually use their wings to hover slightly above the water’s surface and they only skim it with their feet.
Detailed explanation-2: -Water striders are small insects that are adapted for life on top of still water, using surface tension to their advantage so they can “walk on water.”
Detailed explanation-3: -Water striders are able to walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water. Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight.
Detailed explanation-4: -Answer and Explanation: Some insects, such as water striders, are able to walk on water. This is due to the phenomenon of surface tension. Since water has a high surface tension due to strong intermolecular forces like hydrogen bonding; the surface of the water is pulled inwards to reduce surface area.
Detailed explanation-5: -Small insects such as water strider can walk on water due to which phenomenon (choose the best one) A. Viscosity.
