Some insects, such as the water strider, can literally walk on water. The property of water that allows the water strider to stay on the surface of the water is termed
|
|
polarity
|
|
|
adhesion
|
|
|
surface tension
|
|
|
specific heat capacity
|
Explanation:
Detailed explanation-1: -Surface tension allows a water strider to “walk on water"
Detailed explanation-2: -Because of hydrogen bonding, water can actually support objects that are more dense than it is. Water molecules stick to one another on the surface, which prevents the objects resting on the surface from sinking. This is why water striders and other insects can “walk” on water!
Detailed explanation-3: -The water strider’s secret is its legs. The legs have tiny hairs that repel water and capture air. By repelling water, the tiny water striders stand on the water’s surface and the captured airs allows them to float and move easily.
