Combustion Practice Test

Combustion is a chemical reaction that occurs between a fuel and an oxidizing agent, typically oxygen, resulting in the release of heat, light, and the formation of new substances. It is a rapid exothermic reaction characterized by the ignition of the fuel and the sustained release of energy. Combustion requires three essential components known as the "fire triangle": fuel, oxygen, and heat. When these elements are present in the right proportions, combustion can occur. The fuel can be in various forms, such as gases, liquids, or solids, while oxygen is typically obtained from the surrounding air. The heat necessary to initiate and sustain the reaction can come from an external source or be generated by the combustion process itself. Combustion is a vital process that powers various applications, including heating, transportation, and energy generation. However, it also produces byproducts such as carbon dioxide, water vapor, and other pollutants, making it crucial to manage and control combustion processes to minimize environmental impact.
