When measuring temperature, the usual units are Celsius (degree Celsius) or Fahrenheit (degree Fahrenheit). Most volatile compounds (anywhere near ambient temperatures) go through an intermediate liquid phase while warming up from a solid phase to eventually transform to a vapor phase. (Image credit: Shutterstock/ChameleonsEye), Fahrenheit: The first precise thermometer. The boiling point corresponds to the temperature at which the vapor pressure of the liquid equals the surrounding environmental pressure. Another factor that affects the normal boiling point of a compound is the polarity of its molecules. The simple answer to this question is that the boiling point of water is 100 C or 212 F at 1 atmosphere of pressure ( sea level ). As you gain altitude (e.g., ascending a mountain), water boils at a lower temperature, and as atmospheric pressure rises, it boils at a higher temperature (coming back down to sea level or going below it). Water boils at 100 C (212 F) at sea level (0 m), where pressure is higher. I'm sick and I'm trying to get my humidifier to put as much water in the air as possible. When the molecular size becomes that of a macromolecule, polymer, or otherwise very large, the compound often decomposes at high temperature before the boiling point is reached. It describes the amount of kinetic energy contained by the particles that constitute a blob of matter, that wiggle and jiggle around at sub-microscopic levels," she said. Beyond its triple point, a compound's normal boiling point, if any, is higher than its melting point. Other people also believe that baking soda and pepper may raise the boiling temperature of the water. Primordial From decay SyntheticBorder shows natural occurrence of the element.
