Explain the following using a property of a liquid. A very light insect can walk on water without falling?
Answer:
Surface tension. The insect can walk on it because it never breaks the surface tension, which is the force holding molecules at the surface together. You can see this when you fill a glass up all the way, and it looks like the liquid is kind of bubbling out over the top of the glass a little.
The liquid has Surface Tension.

I was thinkin surface tension and/or capillary action.
Surface tension keeps most insects up,but if their feet are wetted by the surface they will sink.
The property is called ' Surface Tension '. This link will explain it :

Hope this helps.
It is called surface tension. It is the same principle that causes a water droplet to bead on a surface rather than to spread out to infinity.
Surface tension. If you want to do a little experiment with it, try this.
You will need a glass, water, a needle and probably some tweezers. (or something to hold the needle with)
Fill a glass completly up so that there is water above the rim of the glass, but not coming out. It should look like there is a bubble of water just above the rim. Take the tweezers and place the needle on top of that bubble. Lay it flat so that it floats. If done correctly, the needle will float on top of the water, the same way a small insect walks on top of the water.
because of surface tension of liquid
