properties of water

Importance of Water

Water is the biological medium on Earth, and all living organisms require water more than any other substance.

Water Facts

Three-quarters of the Earth's surface is submerged in water, making it habitable.

Water Structure

A water molecule consists of one oxygen atom and two hydrogen atoms in a V-shape.

Water Polarity

Water molecules have polarity due to unequal sharing of bonding electrons, resulting in partial charges.

Cohesion

Cohesion is the bonding of water molecules to each other, helping pull water upward in plants.

Adhesion

Adhesion is the bonding between unlike molecules, helping water adhere to vessel walls.

Surface Tension

Surface tension is the measure of how difficult it is to break the surface of a liquid.

Specific Heat of Water

Water has a high specific heat, allowing it to resist temperature fluctuations.

Evaporative Cooling

Evaporation transforms liquid to gas, cooling surfaces as heat is absorbed to break hydrogen bonds.

Insulation by Ice

Ice is less dense than water, insulating aquatic life below its surface.

Universal Solvent

Water is called the universal solvent because many substances dissolve in it.

Dissociation of Ions in Water

Ions and polar groups become surrounded by water molecules, leading to their dissociation.
