The "burning" that takes place in a star is not the same as the fire you fine on Earth. Stars are powered by a process called nuclear fusion in which atoms of hydrogen fuse together to form helium. Nuclear fusion releases far more energy than combustion. The energy released by fusing one kilogram of hydrogen in the sun is equivalent to burning 38 million metric tons of dry wood.
presence of oxygen. Oxygen is necessary for combustion to occur and sustain a fire. Without oxygen, a fire cannot burn.
Phosphorus is an element that can burn without oxygen through a process called spontaneous combustion. When exposed to air, phosphorus can react with the oxygen in the air to produce phosphorus oxide and ignite.
Oxygen is not flammable, but it is a powerful supporter of combustion. It does not burn itself, but it can cause other materials to burn more easily by providing the necessary conditions for combustion.
No. Oxygen itself is not flammable, but it is necessary for fire. Fire is a chemical reaction between oxygen and a flammable substance. Fire is possible on Earth because ordinary air is 21% oxygen. Pure oxygen is considered a fire hazard because higher concentrations of oxygen will make it easier for a fire to ignite and will allow it to burn hotter and faster than normal.
Oxygen is the element in the air that is needed for coal dust to burn. When coal dust is exposed to oxygen and heat, it can ignite and burn.
The sun and other stars don't burn oxygen, they burn other gases. that's what a star is, a big ball of gas. It burns these gases, which is also what is used to classified the stars into Main Sequence stars, Giants, Dwarfs, etc. The sun and other stars don't burn oxygen, they burn other gases. that's what a star is, a big ball of gas. It burns these gases, which is also what is used to classified the stars into Main Sequence stars, Giants, Dwarfs, etc. from the answer on the top.. the sun does not burn oxygen... is eats up the oxygen and make carbon dioxide.
True, fire must have oxygen to burn.
The rocket carries its own supply of oxygen with which to burn the fuel.
Yes, young stars burn Hydrogen and produce Helium. As they age, they often turn into red giants, and at that time they burn the Helium, making Oxygen and Carbon. Very large stars can even burn the Oxygen and Carbon, making even heaver elements, such as Iron.
NO!! (not to be harsh)
The "burning" inside a star is not fire as we are familiar with it, which is called combustion. Stars are powered by nuclear fusion. Combustion is a chemical process by which oxygen combines with other substances to make new molecules. In nuclear fusion, hydrogen atoms fuse with each other to form helium. This process produces millions of times more energy than combustion does.
>>>MoonBecause there is no oxygen, fire needs air to burn.
No, fossil fuels do not produce oxygen when they burn. Instead, the combustion of fossil fuels releases carbon dioxide and other greenhouse gases into the atmosphere. This process contributes to air pollution and climate change.
When coal is burned without oxygen, it undergoes a process called pyrolysis where it decomposes into volatile gases, tar, and char. This can produce useful byproducts such as charcoal and coal gas, which can be used in various industrial processes.
The color of the stars depend on how hot they burn.
No, chlorine gas itself does not burn without oxygen present. Burning refers to a chemical reaction with oxygen to produce heat and light. Chlorine can react with other substances in a way that resembles burning, such as when it combines with certain metals to form metal chlorides, but this is not combustion in the traditional sense.
Titanium burns in nitrogen as well as oxygen. You might get some argument that combustion mean "in oxygen" but I think it is fair to say that lots of things "burn" in something other than oxygen. They undergo chemical reactions while giving off light and heat.Combustion is a process in which some is oxidized in an exothermic reaction. Things can be oxidized by other chemicals than oxygen, such as Cl2 or F2, and that would be considered combustion.Pyrolysis is a thermochemical reaction in which organic matter undergoes decompostion(or combustion in another sense) in the absense of oxygen.This is a clear example of combustion without oxygen.See the Web Links to the left for more information.
