This study examined internal phosphorus release in a thermally stratified fresh water body in upstate New York. Divide this value by .0500 g white phosphorus to get the enthalpy of combustion in J per gram. A match is lit by the striker box, which causes friction and enough heat to ignite the match. 1.1 SOURCES OF IGNITION - GENERAL TEMPERATURES; 1.2 COLOR TEMPERATURES OF HEAT Red phosphorus can be produced by heating white phosphorus to 250 degree Celsius in air absence or by exposing it to sunlight. Often ignites on contact with air; storage under water prevents this reaction. Naphthalene is obtained from either coal tar or petroleum distillation and is primarily used to manufacture phthalic anhydride, but is also used in moth repellents. White phosphorus consists of discrete P 4 molecules.
