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 main difference between the scales of temperature lies on the relative values for freezing and boiling points. In Celsius, water boils at 100Â°C while its freezing point is at 0Â°C. In Fahrenheit scale, water boils at 212Â°F while its freezing point is at 32Â°F.
