Water is a universal solvent. This means it...

• Causes other substances to be attracted to it

• Can move against the force of gravity

• It can be attracted to itself

• It can dissolve most substances because it is polar

Ice floats because...

• It is more dense as a solid than as a liquid

• It is less dense as a solid than as a liquid

Adhesion is...

• The property of water that causes it to be attracted to other substances

• The property of water that causes it to be attracted to itself

Cohesion is...

• Property of water that causes it to be attracted to itself.

• Property of water that causes it to be attracted to other substances.

In its ICE form water..

• is loosely packed, molecules move faster, higher energy

• tightly packed molecules, low enery

• molecules move fastest, highest energy
