What is Flame?
A flame is the visible, luminous, gaseous part of a fire. It occurs when a combustible substance reacts with an oxidizing agent, typically oxygen, in a process known as combustion. Flames emit light and heat as a result of the chemical reaction, and their color and appearance can vary depending on factors such as the type of fuel, temperature, and the presence of specific elements or impurities.
Flames can be different colors, depending on the fuel that is being burned. For example, a blue flame indicates that the fuel is burning completely. A yellow flame indicates that the fuel is not burning completely. A green flame indicates that the fuel contains copper. A red flame indicates that the fuel contains lithium. Flames can be used for a variety of purposes, such as cooking, heating, and lighting. They can also be used to power engines and to generate electricity.
What is Flame and Structure of Flame – NCERT Class-8 Notes
What is Flame and Structure of a Flame – NCERT Class-8 Notes: A flame is the visible part of a fire. It is a hot, glowing gas that produces light and heat. Flames are usually caused by a chemical reaction between a fuel and an oxidizer. The fuel is typically a hydrocarbon, such as wood, gas, or oil. The oxidizer is usually oxygen, but it can also be another substance, such as chlorine or fluorine. When a fuel and an oxidizer are mixed in the right proportions, they will react to produce heat and light. This reaction is called combustion. The heat from the combustion reaction causes the gas to expand and glow, creating a flame.
In this article, we will look into the meaning and structure of flame. It is an important concept of class 8 Science. Students can go through this article to get comprehensive notes on the meaning and structure of flame.
