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..
Water boils at 212 degrees on the Fahrenheit scale, which is 100 degrees on the Celsius scale, but only at sea level at a specific air pressure. If you boil water, say, half-way up Mount Everest, the boiling point temperature is so low that it is very difficult to cook food.
