Detailed explanation-1: -Furthermore, water molecules interact through hydrogen bonding to create 3 very unique properties: cohesion, adhesion, and surface tension. Cohesion is the ability of water to “stick” to itself. The hydrogen bonding between water molecules means they are more likely to stick together than break apart.

Detailed explanation-2: -The correct answer: The true statement about the hydrogen bond is c. Hydrogen bond is weak force between atoms in a molecule but is of enormous importance in physiology.

Detailed explanation-3: -This intermolecular bonding between water molecules gives water distinct properties not seen in other substances: Thermal properties – Water can absorb much heat before changing state (requires breaking of hydrogen bonds)

Detailed explanation-4: -This type of bond can occur in inorganic molecules such as water and in organic molecules like DNA and proteins. Hydrogen bonds are responsible for holding materials such as paper and felted wool together, and for causing separate sheets of paper to stick together after becoming wet and subsequently drying.
