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 âboiling temperatureâ of water at a given pressure is a saturation temperature â the temperature at which water vapour and liquid are both stable (at that pressure). It is not exactly the temperature at which water boils, unless the water is heated so slowly (and mixed so well) that no bubbles ever form, and all the boiling is actually evaporation from the surface.
