Which of the following is a correct statement about water?

hydrogen bonding causes water to be strongly cohesive.
hydrogen bonding causes water to have a low surface tension.
water is a universal solvent because polar and nonpolar solutes can dissolve in it.
water is less dense as a liquid than as a solid because of changes in bond structure.

Answer;

Hydrogen bonding causes water to be strongly cohesive.

Explanation;The strong hydrogen bonds give water a high cohesiveness and, consequently, surface tension.Hydrogen bonding makes ice less dense than liquid water and since ice is less dense than water, it is able to float at the surface of water.Water is considered the universal solvent due to its ability to dissolve or dissociate most compounds, a property that results from its polarity, where oxygen has a higher electronegativity than hydrogen.
