The States or Phases of Water
- Water is known to exist in three different states; as a solid, liquid or gas.
- Clouds, snow, and rain are all made of up of some form of water.
- A cloud comprises tiny water droplets and/or ice crystals, a snowflake is an aggregate of many ice crystals, and rain is just liquid water.
- Water existing as a gas is called water vapour.
- When referring to the amount of moisture in the air, we are actually referring to the amount of water vapour.
- If the air is described as "moist", that means the air contains large amounts of water vapour.
- Steam is water in the gas phase.
- It is commonly formed by boiling or evaporating water.
- Steam that is saturated* is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapour condenses. (As on a window in winter.)
- *A liquid that is about to turn to vapour.
