What is the flame definition in science?
flame, rapidly reacting body of gas, commonly a mixture of air and a combustible gas, that gives off heat and, usually, light and is self-propagating. Flame propagation is explained by two theories: heat conduction and diffusion.
What is in a flame?
Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire’s intensity will be different.
What is flame and examples?

How a flame is formed?
Fire is the result of a chemical reaction called combustion. At a certain point in the combustion reaction, called the ignition point, flames are produced. Ordinarily, flames consist primarily of carbon dioxide, water vapor, oxygen, and nitrogen.
What is flame and types of flame?
There are three types of flames natural flame, carburizing flame and oxidizing flame. Natural flame has synchronized mixture of fuel and oxygen, carburizing flame has more fuel and oxidizing flame has more oxygen.

The acronym FLAMES stands for Friends, Lovers, Affectionate, Marriage, Enemies, and Siblings. To play the game, first write your name and your crush’s name on a piece of paper. Then, cross off any letters that your names share. Total the number of leftover letters between each of your names.
What are the properties of flame?
Flame is a mixture of gases (vaporised fuel, oxygen, carbon dioxide, carbon monoxide, water vapour, and many volatile materials). The flame produces energy (i.e., heat and light). The flame is not a matter, but fire is a matter. Flame is a chemical reaction.
Is flame a gas?
Fire is a plasma, not a gas or a solid. It’s a kind of transient state between being composed of the elements prior to ignition and the spent fumes (Smoke – solid particles and Gasses = Gas molecules.)
What is the meaning of this emoji 🔥?
The fire emoji is a flame that is mostly yellow with a little red on the top. It is used to signify that something is cool, awesome, exciting, or more colloquially, “on fire.” It can also convey that someone is sexy, (i.e., hot), or refer to other various metaphorical fires.
How does a flame work?
Fire is the result of applying enough heat to a fuel source, when you’ve got a whole lot of oxygen around. As the atoms in the fuel heat up, they begin to vibrate until they break free of the bonds holding them together and are released as volatile gases. These gases react with oxygen in the surrounding atmosphere.
What is a flame class 8?
Flame: A region of burning gases is called flame.. A substance will burn with a flame, only if some gaseous substance is there to burn.
What is structure of a flame?
It is made up of a solid block of fuel with an embedded wick. A candle flame consists of three zones. Namely, the outer zone or non-luminous zone; this is the hottest zone, the middle zone or luminous zone; this zone is moderately hot, and the innermost zone or dark zone; there is no combustion in this zone.
What is a burning flame?
A flame is a hot bright stream of burning gas that comes from something that is burning.
What is a flame class 10?
A flame is the visible, gaseous part of a fire. The substance which vaporise during burning give flames, It is caused by a highly exothermic reaction taking place in a thin zone. A hot glowing body of gas that generates fire is called flame.
How hot is a flame?
Deep red fire is about 600-800° Celsius (1112-1800° Fahrenheit), orange-yellow is around 1100° Celsius (2012° Fahrenheit), and a white flame is hotter still, ranging from 1300-1500 Celsius (2400-2700° Fahrenheit). A blue flame is the hottest one of all, ranging from 1400-1650° Celsius (2600-3000° Fahrenheit).
Why do flames move?
The pull of gravity draws colder, denser air down to the base of the flame, displacing the hot air, which rises. This convection process feeds fresh oxygen to the fire, which burns until it runs out of fuel. The upward flow of air is what gives a flame its teardrop shape and causes it to flicker.
Is fire a energy?
The flame itself is a mixture of gases (vaporized fuel, oxygen, carbon dioxide, carbon monoxide, water vapor, and many other things) and so is matter. The light produced by the flame is energy, not matter. The heat produced is also energy, not matter. Fire changes the nature of substances.
What is natural flame?
Definition of neutral flame : a flame resulting from the burning of gases supplied in the proper proportions for perfect combustion (as approximately equal volumes of acetylene and oxygen)
What is the hottest flame?
Blue flames are the hottest, followed by white. After that, yellow, orange and red are the common colours you’ll see in most fires. It’s interesting to note that, despite the common use of blue as a cold colour, and red as a hot colour – as they are on taps, for instance – it’s the opposite for fire.
What is the name of gas flame?

Natural flame has a synchronized mixture of fuel and oxygen, the carburizing flame has more fuel, and oxidizing flame has more oxygen. Different materials used different flames according to weld condition.
