Explanation:
Detailed explanation-1: -The high surface tension helps the paper clip-with much higher density-float on the water. The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.
Detailed explanation-2: -The paper clip is more dense than water but can rest on the surface of the water because of the water’s surface tension.
Detailed explanation-3: -A metal needle or paper clip has higher density that that of water. So when it is dropped into water, it falls down into the bottom of water. However, if we put it horizontally on the water with a lot of caution, it can float almost forever due to the surface tension of water.
