Matter is anything that takes up space and has weight
Earth’s water is found in the liquid state in oceans, lakes, and rivers.
Earth’s water changes state: glaciers melt, dripping water forms icicles, puddles dry up and water vapor becomes drops of dew.
Evaporation is the change of matter from a liquid to a gas.
You may see a cloud of “steam” rising from a pot of boiling water. What you see is not water vapor. Water vapor is a clear, colorless gas. The cloud is a mist, made up of tiny droplets of liquid water that condense from water vapor.
When water vapor loses heat, its particles move more slowly. They move closer together. The water vapor changes to liquid water.
When the air cools at night, the drops of water called dew form on the grass. How do the drops form? Why do they disappear during the day?
2. Which statement BEST describes what happens to water when it changes state from a liquid to a solid?
