Why does a matchstick not catch fire on its own at room temperature
Match stick does not burn on its own because temperature is less than the ignition temperature.
On stricking with the walls of match box, sufficient amount of heat is produced due to friction which raises the ignition temperature of the chemicals on the match stick and thus burns..
What are the 4 stages of fire
Compartment fire development can be described as being comprised of four stages: incipient, growth, fully developed and decay (see Figure 1).
Why do materials burn
In burning, the two atoms or molecules will combine and release energy. Usually one of the two molecules is oxygen or something else chemically like it called an oxidizer. When the molecules combine and release energy, it is released in the form of heat and often light.
Why did kerosene oil catch fire faster than wood
Q11: Why does kerosene oil catch fire faster than wood? Ans: This is because the specific heat capacity of the wood is more than the kerosene oil. So, the wood takes time to burn but burns for longer period than the kerosene oil.
Which gas is required for burning
OxygenThree things are required in proper combination before ignition and combustion can take place—Heat, Oxygen and Fuel. There must be Fuel to burn. There must be Air to supply oxygen.
What is a flame what actually burns to produce a flame
All the gases which undergoes combustion produces flame. But only those solids and liquid fuels which vaporise on being heated,burn with the flame. Some of the substances which burn by producing flames are LPG, CNG, biogas, wax, camphor, magnesium, kerosene oil, mustard oil.
What items can you burn to produce heat
A fuel is a material that can be burned to produce heat, light or power. Examples of fuel include wood, coal, natural gas, and oil.
Why the flame flickers when a glass chimney put over the candle
We find that for combustion, air is necessary. The candle burns freely in case (a) when air can enter the chimney from below. In case (b), when air does not enter the chimney from below, the flame flickers and produces smoke.
Which fuel does not burn with a flame
Liquefied petroleum gas (LPG), also referred to as simply propane or butane are flammable mixtures of hydrocarbon gases, used as fuel in heating and cooking equipment and produce a blue flame. Camphor gives a flame, which is widely used in worship. Charcoal, does not vaporise and so, does not produce a flame.
What is difference between burning of candle and burning of coal
Candle burns with a flame but coal burns with only a glow. This is because only substances that vapourize while burning gives flame. Thus candle burns with a flame because it vapourizes while burning and coal burns with a glow because it does not vapourize while burning.
What is burning of fuel called
Burning a fuel is called combustion, a chemical process that we study in middle or high school. … Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat.
What produces a flame
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. Flames consist primarily of carbon dioxide, water vapor, oxygen, and nitrogen.
Is purple fire hotter than blue fire
As things heat up and combustion becomes more complete, flames turn from red to orange, yellow and blue. And purple color is combination of red & blue color it means that blue fire is more hotter than purple fire. … At hotter temperatures, the flame color moves into the blue-violet end of the visible spectrum.
Can fire exist without oxygen
A fire cannot burn without oxygen. … The burning that a star does, then, is a nuclear reaction, and not a chemical one like the fires on Earth (when a candle burns, the atoms themselves remain unchanged: just the molecules are affected).
