  "definition": "1. The liquid that descends from the clouds as rain, forms streams, lakes, and seas; and is a major constituent of all living matter and that is an odorless, tasteless, very slightly compressible liquid oxide of hydrogen H2O which appears bluish in thick layers, freezes at 0 degrees Celcius ( 32 degrees F) and boils at 100 degrees Celcius (212 degrees F).\n\n2. A colorless, transparent, odorless, tasteless liquid compound of hydrogen and oxygen. The liquid form of steam and ice. Fresh water at atmospheric pressure is used as a standard for describing the relative density of liquids, the standard for liquid capacity, and the standard for fluid flow. The melting and boiling points of water are the basis for the Celsius temperature system. Water is the only byproduct of the combination of hydrogen and oxygen and is produced during the burning of any hydrocarbon. Water is the only substance that expands on freezing as well as by heating and has a maximum density at 4°C.\n\n3. Unspecified flowable for H2O, not a preferred term [Original source: https://cfpub.epa.gov/si/si_public_record_Report.cfm?dirEntryId=347251&Lab=NRMRL].",
