Water Properties and Concepts

Front

• When water molecules stick to each other

• Example: water forming droplets

Back

Cohesion

Front

• When water molecules stick to other things

• Example: Water sticking to a leaf

Back

Adhesion

Front

• Water molecules have a positive and a negative end.

• This makes them act like magnets

Back

Polarity

Front

• How heavy something is compared to its size

• Example: ice floats in water because it is less dense as a solid

Back

Density

Front

How well something can dissolve in water.

Example: sugar disappears when you stir it in your drink but oil does not dissolve

Back

Solubility

Front

When water molecules stick together (cohesion) and create a “membrane-like” surface

Allows some insects to walk on water

Back

Surface Tension

Front

The movement of water in a narrow space. When water “climbs”

Example: water climbing up a paper towel

Back

Capillary Action

Front

All the water on Earth. Includes oceans, lakes, rivers, and even water in the air.

Hydrosphere

Front

The different forms water can take: solid (ice), liquid (water), and gas (water vapor). Water can change between these states when heated or cooled.
