Question

Why does water have a high surface tension? (2 points) Hydrogen bonding keeps water molecules close together. Water is a liquid at room temperature. The lengths of the bonds in water molecules can change. Water molecules contain 18 electrons.

Answer 1

Answer: Because water contains hydrogen bonds.

Explanation: Despite being weak bonds, hydrogen bonds cause water to have what is called surface tension. Objects can float on water due to this.

Answer 2

The correct answer is A. Hydrogen bonding keeps water molecules close together.

Explanation:

In physics, surface tension refers to the tension that is created in the surface of liquids as a result of bonds or attraction between particles and that makes the surface layer denser than the rest of the liquid. In the case of water, this occurs due to the bonds created between the hydrogen particles with other particles in water that create a surface that is denser and flexible. This only occurs in the surface while particles in the rest of the liquid do not form these bonds. Considering this, it can be concluded water has a high surface tension because "hydrogen bonding keeps water molecules close together".
