Detailed explanation-1: -Answer and Explanation: Some tiny insects are able to walk on water because of the surface tension on the top of the water that is due to water’s cohesive properties. Water is cohesive, or ‘sticky, ’ because water molecules are attracted to each other, due to the polarity of the molecule.

Detailed explanation-2: -Insects can walk on water because of a phenomenon called surface tension. This is essentially a property of water (or any liquid) which allows it to resist an external force.

Detailed explanation-3: -Water molecules are bent so the hydrogen atoms are to one side of the oxygen atom. and when it come to molecules opposites attract. A bond forms between the negative side of one water molecule and the positive side of another. At that is what gives water its stickiness.

Detailed explanation-4: -Water is highly cohesive-it is the highest of the non-metallic liquids. Water is sticky and clumps together into drops because of its cohesive properties, but chemistry and electricity are involved at a more detailed level to make this possible.
