Practice Other Topics from Combustion and Flame
The topic focuses on the process of combustion. It acquaints us with the process of burning and categorises substances based on their combustibility. Substances can be combustible or non-combustible, which are defined with the help of examples.
In this topic, we will learn about the conditions necessary for the process of combustion. These conditions include that the substance should be flammable, there should be oxygen, and there should be a specific ignition temperature.
The topic tells us about fire fatalities and how to handle the situation, and control fire, if any. The ways of extinguishing a fire are mentioned. It warns us against using water to stop all fires. We also study the working of a fire extinguisher.
The topic provides knowledge about flame. We will understand the reasons why some substances burn with a flame, while others burn without a flame. This theory is explained through the examples of kerosene, candle, and charcoal.
