In combustion of methane (CH 4 ), the heat flow intothe surroundings results in a lowering of thepotential energy of the reaction system (this alwaysholds true).In any exothermic reaction, the potential energystored in the chemical bonds is being converted tothermal energy (r<strong>and</strong>om kinetic energy) via heat.Copyright©2000 by HoughtonMifflin Company.
