how does paper burn?

Answer 1

Combustion or burning is a complex sequence of chemical reactions between a fuel and an oxidant accompanied by the production of heat or both heat and light in the form of either a glow or flames.

The commonly accepted autoignition temperature of paper, 451 °F (233 °C), is well known because of the popular novel Fahrenheit 451 by author Ray Bradbury (although the actual autoignition temperature depends on the type of pulp used in the paper's manufacture, chemical content, paper thickness, etc.)

Paper curls when it burns becuase the heated side loses water faster than the opposite side which then shrinks and curls the sheet away from the heat.

Answer 2

The same way everything else burns: by rapidly combining with oxygen.

In order for anything to burn, three components must be in place:

1) Fuel. You must have some substance ready to oxidize.
2) Oxygen. Obviously, you have to have oxygen available in order to oxidize something. Some fuels, like gunpowder, contain oxydizers (chemicals that store oxygen), and can provide their own oxygen to sustain the reaction.
3) Heat. Every substance has a "flashpoint", the temperature at which the molecules of that substance become unstable enough to begin oxydizing. In the case of paper, that temperature is 451 degrees Farenheit. (Immortalized in Ray Bradbury'sclassic sci-fi novel "Farenheit 451".)

Paper molecules, like all organic molecules, are made of carbon, hydrogen, and oxygen atoms. In a burn reaction, these molecules break apart, and the atoms reform into simpler molecules: water vapor, carbon dioxide, carbon monoxide, etc.

Answer 3

Paper burns due to the carbon present in the form of cellulose. When enough heat is applied to the paper in the presence of oxygen (no flame is necessary), the energy required to convert the carbon to carbon dioxide is reached and the reaction (the paper burning) can take place.

Answer 4

Paper mostly is made of cellulose a heavy polysaccharide which takes up heat received by conduction ,convection and radiation. When heat reaches the maximum quantity it breaks up into carbon,oxygen ,hydrogen and other ingredients like dye .Carbon in presence of oxygen burns.

Answer 5

paper is made from wood.and wood will burn. So there.

Answer 6

heat + fuel = fire
pretty simple...paper is carbon based and carbon is a pretty good fuel.

Answer 7

Quite quickly if you run it across it your flesh "quite quickly"

Answer 8

give me a lighter and ill show u

Answer 9

yes it does and you can try it to see if it does catch on fire

Answer 10

very well. particularly if it's on fire at the time.
