Strike a light! A match bursts into flames after being struck. This match,of the 'strike anywhere' kind,consists mainly of phosphorus sesquisulphide and potassium chlorate in the head. When the head is run across a rough surface,friction heating allows an exothermic oxidation reaction to take place. The excess heat developed is sufficient to ignite the wood of the match stick | |
