States of Water
Water is one of the few things that is found in nature as a solid, liquid and a gas
2
There are three states of matter
Solid, liquid, gas
3
Solid Water - Ice
When water freezes, it expands or gets bigger.
Molecules vibrate back and forth but do not move to different positions.
Ice floats in water because
it is less dense.
4
Liquid - Water
molecules move freely so sometimes they
bump into each other.
most things dissolve in water which makes water the universal solvent.
greatest range of temperatures
very cold water to very hot water.
5
Gas - Water Vapor
molecules move quickly and far apart.
water in a gas state is called water vapor.

The Water Cycle
The Sun provides the heat which can make water change from one state to another.
12
Evaporation
Evaporation - heat from the Sun makes the liquid water molecules move faster and evaporate or change into a gas.
Liquid to a gas.
Temperature increases.
13
Condensation
Condensation - water vapor molecules floating in the air cool down and change back into a liquid (clouds).
Gas to a liquid.
Temperature decreases.
14
Precipitation
Precipitation - the water drops in the cloud get bigger and bigger (cohesion) until eventually they fall as rain or snow.
