Is charcoal combustible whenever it gets wet?

Fire is the result of a combustion chemical reaction in which a hydrocarbon (a compound containing carbon and hydrogen) is reacted with oxygen forming carbon dioxide and water.  This reaction releases a lot of energy in the form of thermal (heat) radiation which is the result of fire.\n\nNote that there are other compounds which react with oxygen to release much energy and form oxides, but they're not relevant with respect to water.\n\nIce is water and not a hydrocarbon so it can not catch on fire.

the conclusion is that when you heat water it will boil.\nif you donot stop it will ecoporate

I believe it would definitely combust... as soon as it heats up.\n\nGasoline combusts at around 1950 degrees Celsius. So if you take gasoline that's at -120 degrees, you'll need for it to heat up before it combusts.\n\nFirst Law of Thermal Dynamics and the Adiabatic combustion temperatures should help explain how all this works.\n\nDon't forget that you wouldn't ever have a burning cube of frozen gasoline. As the outside of the cube begins to melt, it will burn and evaporate... think about the way a water ice cube melts if you were to light a fire under it.

Yes, and yes. \n\nWhen organic compounds are burnt, their combustion reaction usually yeilds a range of colours from red to yellow. However, when hydrocarbons such as methane or ethane are burnt, their combustion reaction produces sufficient heat to produce a wider spectrum of colours such as blue. \n\nA combustion reaction occurs when sufficient heat is applied. If enough water is added to reduce the temperature to below that which produces the required activation energy (that is including the actual compound and its environment), then the flame will go out.

Charcoal filters are basically clean carbon with many more times surface area when compared to their mass.  The charcoal absorbs other carbon based impurities which are the main contributors to bad tastes and smells.  Things in clean air (nitrogen, oxygen, etc...) are not carbon based and therefore do not absorb onto the filter.  Water does not absorb due to the same reason.  Alcohol will absorb to the charcoal filter, depending on the effectiveness of  the filter as well as the flow rate not all the alcohol will be removed from the drink.  When looking at a complex mixture of compounds there is a competition for the absorbent.  Some things are more likely to absorb than others.

You cannot combust water, it is already the result of the combustion of hydrogen in the presence of oxygen.

Once something has already burned, it will not burn again. Water is the result of hydrogen burning.

fire as in flames,in the water...

Yes.  The methane and hydrogen, the main ingredients, are flamable.  The perfect circumstances?  That's a tough one.  Perhaps if you were a bit stoned so that it would be humorous?

It can set the gasoline on fire. Eventually there could be an explosion. I've seen films of people being lit on fire while pumping gas. \nHere's a link that verifies fire can happen.\n.

Celestine is sometimes used to produce a red color in fireworks. Charcoal (carbon) is also used in pyrotechnics. Charcoal from soft woods, such as grape vine or willow, is good for fast-burning compositions like black powder, whereas charcoal from hard woods like pine are used to create long-lasting spark effects. \n\nIn any laboratory setting proper personal protection equipment should be employed. I recommend using safety glasses, a laboratory coat, full length pants and latex/polyethylene gloves. You shouldn't wear open toed shoes and loose articles of clothing that could snag. In cases were an explosion is possible, proper shielding is required. A fume hood is also required if hazardous fumes are expected.\nAlso, if you are resorting to using an online forum to recieve answers to potentially dangerous reactions, you obviously do not know what you are doing and should gently place down your little pyrotechnics and slowly back away.

Foams are primarily used on fires involving flammable liquids.  Foam is still water based, so you would never want to use it on an electrical fire!\n\nAs mentioned in a couple other answers, foam cuts off the oxygen supply to a fire and it also has a cooling effect, like water.  It's particularly suited to suppress flammable liquid fires because of it's foamy nature.  The foam "floats" over the surface of the burning fuels covering and cooling the area.  Most flammable liquids are lighter than water, so using water alone could actually spread the fire!

Definitely not water, as those three metals will burn on contact with water (and potassium will explode.) Liquid CO2 might do, as it would cool the burning material extensively, possibly below the ignition point. The sand (SiO2) would be a smothering agent. I'm not sure about the carbon tet.\n\n5 NOV 06, 1522 hrs, GMT.

I know that Gasoline and the Carbon chained fuels separate into water and thicker part after so much time of storage if exposed to air.  If you keep an inert gas in the container you will be okay.  Doesn't go "bad" per se, but just won't burn after like 5 years of free O2.

since,wateris a compound and a compound can never show the properties of its constituents.that's why water neither burns itself nor supports combustion.similar example is of iron fillings and sulphur.when we make a mixture of them,they do show their their properties But when a chemical reaction occurs and they together make ironsulphate,the new substanse doesn't show their properties that is ironsulphate is not attracted by magnet.

Not pure carbon in pure water, no.  Don't believe me, try sticking a pencil lead (graphite is pure carbon, not actually lead) into a glass of water and see if it dissolves.\n\nBut carbon will dissolve in some solutions.\n\nAs an aside, you think the guy above me might be trying too hard?  A more concise answer is usually preferable.
