一、可燃物燃烧的条件和贝火的方法1.物质燃烧需要三个条件:可燃物,可燃物与氧气(或空气)接触,温度达到可燃物的着火点.三者必须同时具备,缺一不可.2.灭火的方法有隔离或移走可燃物,隔绝氧气(或空气),降低温度到可燃物的着火点以下等三种.二、注意事项1.对于燃烧的概念,一定要明确燃烧是一种氧化反应,常伴随有发光、放热的现象.因此,在书写有关物质燃烧的文字表达式或化学方程式时,不能把反应条件写成燃烧,而应该是点燃.2.对于燃烧的条件,要特别注意燃烧的
First, the combustible combustion conditions and shellfish fire method 1. Material combustion requires three conditions: combustible material, combustible material and oxygen (or air) contact, the temperature reaches the ignition point of combustibles. The three must have both indispensable .2. Methods of extinguishing fire There are three ways to isolate or remove combustibles, isolate oxygen (or air), reduce the temperature below the ignition point of combustibles, etc. 2. Precautions 1. For the concept of combustion, make sure the combustion is one Oxidation reaction, often accompanied by luminescence, exothermic phenomenon.Therefore, in the writing of the material combustion of the text expression or chemical equation, the reaction conditions can not be written as combustion, but should be ignited.2. For the combustion conditions, to Pay special attention to burning
