Explain why a needle or razor blade can be floated on water

Answers

Answered by saritha4260

A needle floats on water due to surface tension. Water has its own surface tension, that is, the molecules of the water inside exert a tension force on the surface molecules. When a needle is placed on the surface, the surface tension is broken and the needle sinks.
