Question

The high specific heat and cohesive forces characteristic of water are a result of Group of answer choices Hydrogen bonding between water molecules Covalent bonds between the O and two H's of water molecules Ionic bonds between the H and OH Dissociation of H2O into H and OH-O

Answer 1

Answer:

A. Hydrogen bonding between water molecules.

Explanation:

Specific heat capacity of water can be defined as the amount of heat a gram of water must lose or absorb in order to change its temperature by a degree Celsius. It is measured in Joules per kilogram per degree Celsius (J/kg°C). Generally, the specific heat capacity of water is 4.182J/kg°C and is the highest among liquids.

Cohesion is a property of water and typically refers to the attraction between molecules of water which holds them together.

The high specific heat and cohesive forces characteristic of water are a result of hydrogen bonding between water molecules. A hydrogen bond is formed in water due to its polarity (opposite charges between water molecules), which causes each water molecule to attract other water molecules. An atom of hydrogen of each water molecule bonds with the electron lone pair on atom of oxygen of a close water molecule.
