Kindling temperature is the lowest temperature at which a substance catches fire and continues to burn. Different fuels have different kindling temperatures. Paper catches fire easily because it has a low kindling temperature. Coal, because of its high kindling temperature, requires much heat before it will begin to burn. Matches are tipped with phosphorus, or some other low-kindling material, to permit the small amount of heat produced by friction to ignite the match.
The property of phosphorus that makes it ideal for use on matches is
a. High density
b. Low kindling temperature
c. Insolubility in water
d. Conductivity of electrical
