Former Republican President Ronald Reagan is widely recognized as one of America's best presidents for economic expansion. But his party's overall economic track record isn't nearly as sterling. Michael Evans/The White House/Getty Images.
Superheated water is liquid water under pressure at temperatures between the usual boiling point, 100 Â°C (212 Â°F) and the critical temperature, 374 Â°C (705 Â°F). It is also known as subcritical water or pressurized hot water..
The boiling point of water is 100Â°C, 212Â°F or 373.15 Kelvin under standard conditions at sea level (at one atmosphere of pressure). The boiling point of water and any other substance depends on the atmospheric pressure, which changes with elevation. At higher altitudes, the pressure is lower, and so water boils at a lower temperature.
