Microsoft has implemented boiling liquid to help keep datacenter servers at reasonable temperatures. The company uses electronic equipment and liquid capable of boiling at 122 degrees Fahrenheit, 90 degrees below the boiling ...
Water vapor
Water vapor or water vapour (see spelling differences), also aqueous vapor, is the gas phase of water. Water vapor is one state of the water cycle within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Under normal atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation. Water vapor is a greenhouse gas along with carbon dioxide and methane.
