What is Flame and Structure of a Flame
What is a flame?
A flame is the visible, luminous, gaseous part of a fire caused by combustion.
What causes a flame to form?
Flames form when a combustible substance reacts with an oxidizing agent, releasing heat and light.
What are the main parts of a flame?
The main parts of a flame include the outer cone (blue region), inner cone (yellow region), and the dark zone between them.
What does the outer blue region of a flame indicate?
The outer blue region of a flame indicates complete combustion, where fuel molecules are fully oxidized.
What is the significance of the inner yellow region of a flame?
The inner yellow region of a flame is where incomplete combustion occurs due to insufficient oxygen.
How does airflow affect flame structure?
Airflow can influence the shape and behavior of a flame by affecting the supply of oxygen and the mixing of fuel and air.
What is Flame and Structure of Flame β NCERT Class-8 Notes
What is Flame and Structure of a Flame β 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.
