Hi Maria, For pure water, the boiling point is 100 degrees Celsius (212 Fahrenheit) at one atmosphere of pressure, and the melting point is 0 degrees Celsius (32 degrees Fahrenheit) at one atmosphere of pressure. At lower pressures (at high altitudes, for example, in Denver, Colorado), the boiling point will be perhaps a couple of degrees lower.
The Celsius scale was originally defined around the boiling and freezing points of water. 100 degrees Celsius at 1 atm pressure. At sea level (101.325 kPa of atmospheric pressure) pure water boils at 100 deg. C The boiling point of water is 99.97 degrees Celsius, or 211.946 degrees Fahrenheit.
