Why do some substance burn with flame while some others not?

Substances that burn with a flame contain volatile components that vaporize and mix with oxygen in the air to produce a flame. In contrast, substances that do not burn with a flame may lack volatile components or not have the necessary conditions for combustion to occur. The presence of carbon, hydrogen, and oxygen in a compound is important for producing a flame during combustion.


Why flame is observed during the burning of a substance?

Flames are the visible byproduct of a chemical reaction between the substance being burned and oxygen in the air. The heat from the initial ignition raises the temperature of the substance, causing it to break down into volatile gases that combine with oxygen to produce heat, light, and flame. The color of the flame can indicate which specific elements are present in the burning substance.


Does ammoniac burn?

Ammonia itself does not burn. It is actually used as a flame suppressant in some applications. However, ammonia can support the combustion of other materials if there is enough oxygen present.


Why use flame tests in forensic science?

Flame tests allow you to get some idea of what substances make up a given sample. It is particularly useful for the identification of polymers, because many of them give off unique burn patterns.


Is pencil lead flammable?

: Pencil "Lead" Is made out of Graphite and graphite is NOT flammable. However some brands of "lead" have a coating that is. If you expose a pice of "lead" to an open flame the coating will quickly burn away, the flame will extinguish, and the "lead" will remain. (still useable)

Why do different substances catch fire at different temperature?

It basically depends upon the saturation of hydrocarbons.Alkanes generally burn in air with a blue flame because %age of carbon is low which gets oxidised completely by the oxygen as copare to unsaturated hydrocarbons,but production of flame depends upon availability of oxygen too, in secant concentration of oxygen sooty flame or no any flame will be observed and substance at that time will produce energy slowly with sooty flame or just smoke only.
