Properties of Water
The word that means water molecules stick to each other.
Adhesion
The chemical formula for water
H2O
Name the 3 phases of water.
Solid, Liquid, Gas (water vapor)
When liquid water turns to solid water.
Freezing
When solid water turns to liquid water
Melting
The word that means water molecules stick to other materials.
Cohesion
Draw a molecule of water
(See answer on whiteboard)
Water Vapor (gas)
When liquid water turns to water vapor
Evaporation
When water vapor turns to liquid water
Condensation
Water is an excellent _____________. This means other materials can dissolve in it.
Solvent
The word that means one side of the molecule is positive and the other is negative.
Polar
The phase of water where molecules are moving the slowest. They can only vibrate.
Solid
When water moves across ground from one place to another, often down a hill or slope.
Runoff
When water gets soaked into the ground.
Infiltration
What percent of both Earth and the human body is water?
70%
How we proved water is polar in class with a balloon.
Ms. Dolan rubbed a balloon on her hair to build up static electricity, then she was able to bend a stream of water with her balloon.
Water vapor is always ___________ which is why we know steam, fog, and clouds are made of liquid water.
invisible
When water vapor moves out of the leaves of plants into the air.
Transpiration
Any form of water that falls from the sky.
Precipitation
This is the ability to absorb heat energy without causing the temperature to rise.
Heat capacity
Draw the arrangement of water molecules as a solid, liquid, and gas.
(See answer on the white board.)
When heat energy is added to water ___________ can change or ____________ can change, but never both at the same time.
temperature
state
How ice/glaciers disappear into water vapor without melting first.
Sublimation
The cause of frost- water vapor freezing into solid water onto a surface like grass or a window.
Deposition
