Answer 1

Answer:

I just answered this same question for my Biology class hope this helps :)

Explanation:

A hydrogen bond is when positive and negative hydrogen forms together; this explains why cohesion sticks molecules together . Because of cohesion, the water molecules stick together and form a surface; this property is responsible for surface tension. Adhesion is the ability for water to stick to other substances; this helps with capillary action. Hydrogen bonding also explains why water's boiling point is higher than some liquid . With this, water has a high specific heat; this is because the water takes a lot of energy to raise (or lower) the temperature. Once again, hydrogen bonding is essential to another property. This property causes water to expand and to have a low density when frozen.
