Questions & Step-by-Step Solutions
A small insect can walk on the surface of water due to which of the following phenomena?
Step 1: Understand that water has a surface that can hold weight due to a force called surface tension.
Step 2: Recognize that surface tension is caused by the attraction between water molecules, which creates a 'skin' on the surface.
Step 3: Realize that small insects, like water striders, are light enough that they do not break this 'skin' when they walk on it.
Step 4: Conclude that the insect can walk on water because the surface tension supports its weight.
Surface Tension – Surface tension is the cohesive force between liquid molecules at the surface, allowing small objects to rest on the surface without sinking.
