| Water is a type of inanimate object. |

| Comment: An instance of ChemicalCompoundTypeByChemicalSpecies and a specialization of #$InanimateThing. Each instance of #$Water is one piece of some (pure or impure) portion of the chemical compound H2O. Instances of #$Water may be in a gaseous, liquid, or solid state (see #$stateOfMatter); they may be salty or not, drinkable or not. Examples include portions of the ocean, such as the BayOfBiscay and the BayOfBengal (see also SeaWater ); bodies of fresh water, such as NiagaraFalls and the GangesRiver ; quantities of chlorinated water (see PoolWater ); and the contents of bottles of tonic water (see SeltzerWater ). Any portion of liquid that consists mostly of water but differs from it in one or more important properties (as does e.g. urine, coffee, and lemonade) is not itself an instance of #$Water, but has an instance of #$Water as its main constituent (see #$mainConstituent). For the specialization of #$Water whose instances are pure, see (#$PureFn #$Water). |
| Structure: |
| All water has some organic matter as a physical part. Some water is included by all americano. |
| Miscellaneous: |
|
| Water is a chemical reactant in rusting, oxalic acid-dissociation, and slake reactions. |
| Water is a chemical product of hydrogen peroxide decomposition, methane combustion, and combustion of a hydrocarbon in air. |
|
| H3O(+) and water form a conjugate acid-base pair. Water and OH(-) form a conjugate acid-base pair. SO42- is a stronger base than water. Water is a stronger base than NO3- |
| Water is a chemical precursor for ammonium nitrate. Pipe that is composed primarily of some water is made primarily of water. The CAS registry number for water is 7732-18-5. At room temperature water has a vapor pressure of 15 millimeters of mercury. |
| At 25 degrees Celsius water has a density of 1 gram per cubic centimeter. |
| The chemical formula for water is H2O. |
