The boiling point of distilled water is 100 degrees Celsius or 212 degrees Fahrenheit. The boiling point of water can be higher or lower depending on several factors.
Altitude has an effect on the boiling point of water, according to the What's Cooking America website. The boiling point of water is about 2 degrees Fahrenheit lower for every 1,000 feet above sea level. Impurities also change the boiling point in water, typically raising the boiling point. Impurities that can be found in water include chemicals added to tap water and minerals found in hard water. Other things that have an effect on the boiling point of water are the weather and the size and shape of the container being used.
