Boiling Points Protocol

The boiling point of a liquid is reached when the total vapor pressure of the liquid is equivalent to the atmospheric pressure.The temperature at which this occurs is called the boiling point.At higher elevations,and thus a lower atmospheric pressure,a liquid will boil at a lower temperature,as less heat is required to increase the vapor Boiling Points for common Liquids and GasesThe boiling point of a substance is the temperature at which it changes state from liquid to gas throughout the bulk of the liquid.At the boiling point molecules anywhere in the liquid may be vaporized.The boiling point is defined as the temperature at which the saturated vapor pressure of a liquid is equal to the surrounding atmospheric Chapter 13 SOLVENTS,FLUOROCARBONS,AND PAINTSdegreasing tanks is heated to the boiling point which is low,relative to waterand the vapors form vapor zone above the liquid solvent.Solvent vapors condense on the cold item and loosen grease and oil,which then enter chemical storage tanks to clean or paint.Acute exposures to most organic solvents cause central ner-vous
