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 can moderate temperature because of the two properties: high-specific heat and the high heat of vaporization. High-specific heat is the amount of energy that is absorbed or lost by one gram of a substance to change the temperature by 1 degree celsius.
