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.
Another scale is the Celsius scale. In the Celsius scale the freezing point of water is set at 0 degrees (centigrade) and the boiling point at 100 degrees (centigrade). This scale exists on 100 divisions, also known as centiscale. In 1948 the centidegrees (centigrade scale) were replaced by the degrees Celsius (o C).efinition of Celsius: The Celsius-scale is defined by the follow two points: 1  The triple point of water is defined as 0.01 o C. 2  One degree Celsius equals the change of temperature with one degree on the ideal gas-scale.
