Boiling The boiling point of water is 100 °C or 212 °F but is lower with the decreased atmospheric pressure found at higher altitudes. Boiling water is used as a method of making it potable by killing microbes that may be present. The sensitivity of different micro-organisms to heat varies, but if water is held at 70 °C (158 °F) for ten minutes, many organisms are killed, but some are more resistant to heat and require one minute at the boiling point of water. Boiling is also used in cooking. Foods suitable for boiling include vegetables, starchy foods such as rice,
Waterless coolant corrosion while the additives remain soluble. Waterless coolant acts as an antifreeze, protecting engines to -40 degrees F. Waterless coolant is generally more expensive than traditional water and ethylene glycol-based coolants. Waterless coolant Waterless coolant is a glycol-based liquid substance that does not contain water. Its boiling point of 375 degrees F is higher than that of water-based coolants and it resists the formation of corrosion. The substance was invented to circumvent the problems of vaporizing water. When water vaporizes, it retains only 4% of its thermal conductivity. So, water-based coolants are safe at temperatures below the boiling point of
