Dihydrogen monoxide is the chemical name for the most common compound on the planet.

Water

Water’s unique properties allow life to occur.

They include: high specific heat- heats slowly and cools slowly

Water

Water’s unique properties allow life to occur.

They include: High specific heat- heats slowly and cools slowly Liquid phase is more dense than solid phase Water can exist as a gas, liquid and solid at the

same time

Water

These properties are due to water’s polar nature.

Water

These properties are due to water’s polar nature.

This is due to the unequal sharing of electrons.

These properties are due to water’s polar nature.

This is due to the unequal sharing of electrons.

The result is the water molecule has a positive and a negative end.

• Hydrogen bonding explains water’s unique properties including:– Surface tension– Cohesion– Adhesion

Surface Tension

Surface tension is the attraction of water molecules at the surface . It is responsible for the meniscus seen in a graduated cylinder.

Cohesion

This term is used to describe water molecules sticking to each other. This is used to describe surface tension.

Adhesion

This term describes how easily water molecules stick to other surfaces. How easily does something absorb water.

Adhesion

Does this have a low or a high cohesive force?
