A fire is exothermic, which means a decrease in the energy of the system as energy is released to the surroundings as heat. The products of a fire are composed mostly of gases such as carbon dioxide and water vapor, so the entropy of the system increases during most combustion reactions. |
| This combination of a decrease in energy and an increase in entropy means that combustion reactions occur spontaneously. |
