Question: Can You Have Combustion Without Oxygen Class 10?

How can there be fire in space without oxygen?

The fire you mentioned burning in absence of oxygen, will be only in the ‘Sun’, that is by nuclear fusion of hydrogen molecules/Atoms, to Helium molecules/Atoms, by self sustaining atomic level nuclear fusion, which needs only very high temp..

Why does a candle burn with oxygen?

Fire is a chemical reaction that creates light and heat from oxygen and fuel. A lit candle needs to draw oxygen from the air in order to continue burning. If you limit the amount of air available, the candle’s flame eventually goes out once it uses up all the oxygen.

What combustion means?

Combustion is the scientific word for burning. In a combustion reaction, a substance reacts with oxygen from the air. Combustion reactions happen at high temperatures, and transfer energy to the surroundings as light and heat. This is why you see flames when things burn.

Does all combustion require oxygen?

There must be Fuel to burn. There must be Air to supply oxygen. There must be Heat (ignition temperature) to start and continue the combustion process.

Can hydrogen be burned?

Hydrogen fuel is a zero-emission fuel burned with oxygen. … Since the weight of hydrogen is less than air, it rises in the atmosphere and is therefore rarely found in its pure form, H2. In a flame of pure hydrogen gas, burning in air, the hydrogen (H2) reacts with oxygen (O2) to form water (H2O) and releases energy.

What gas can burn without oxygen?

People, including scientists, sometimes say that the Sun “burns hydrogen” to make it glow. But that is just a figure of speech. Hydrogen really doesn’t burn, it fuses, into helium. So no oxygen is required!

What is Combustion example?

Combustion reactions occur when oxygen reacts with another substance and gives off heat and light. Burning coal, methane gas, and sparklers are all common examples of combustion reactions. Essentially, any reaction that involves burning something is a combustion reaction.

Can you have combustion without oxygen?

No and Yes. No combustion I S combination with oxygen. There are products that under the right circumstances can ‘ burn’ or even deflagrate or explode, without there is oxygen gas ( in air) available. then oxygen must be available within the component(s) them self.

How can you prove that oxygen is needed for combustion?

Burn a candle on the open on the open area Burn another candle and keep the candle in the table and put glass over the candle. Mark your observations? Candle which is kept on the open area will still burn and the candle kept under the glass sheds. this shows the oxygen is required for candle to burn.

What are the 3 types of combustion?

The three important types of combustion are:Rapid combustion.Spontaneous combustion.Explosive combustion.

How does oxygen help in combustion?

In order to burn this fuel, oxygen is needed, as it is with any fire. The waste products from the combustion process are water and carbon dioxide. Thus, we breathe because oxygen is needed to burn the fuel (sugars and fatty acids) in our cells to produce energy The air we breathe contains about 21% oxygen.

Can butane burn without oxygen?

No, it will not lit without oxygen.

Why is perfect combustion never obtained?

In reality, combustion processes are never perfect or complete. In flue gases from combustion of carbon (as in coal combustion) or carbon compounds (as in combustion of hydrocarbons, wood etc.) both unburned carbon (as soot) and carbon compounds (CO and others) will be present.

How much oxygen is required for combustion?

Oxygen. Air contains about 21 percent oxygen, and most fires require at least 16 percent oxygen content to burn. Oxygen supports the chemical processes that occur during fire. When fuel burns, it reacts with oxygen from the surrounding air, releasing heat and generating combustion products (gases, smoke, embers, etc.).

What are two types of combustion?

Combustion is the act of burning, in which fuel, heat and oxygen release energy. There are several types of combustion, such as internal combustion, diesel combustion, low temperature combustion and other novel forms.
