Is it possible to boil water in a paper bag over a fire?

Should be able to do it, as the water will boil at about 212 degrees and will keep the paper below its approx 450 degree flashpoint. The part of the bag not cooled by the water might burn though

It depends on what is being burned.  Ordinary book paper, for instance, is 451°F.  Different woods would burn at different temperatures, and also depending on the water content the temp would be different.  You need to specify.

This is an interesting question.  Since water is a byproduct of all combustion using anything with oxygen and hydrogen such as fossil fuels or wood or just about anything you can think of that burns it itself does not burn.  If you add alcohol to it the alcohol it self will burn but not the water it will evaporate.  It is not possible to burn water unless you get it back to its original components.  You can do this with electrolosys.  So what you could do is design a car that runs on oxygen and hydrogen.  Take some water home stick 2 electrodes in it and it would turn into oxygen and hydrogen, then you would take those tanks to your car and power it that way.  It would be a very efficient method since the ammount of energy you use to make the gas is the same ammount of energy that you would get from burning the gas.  And Electricity is cheap.  Fossil fuel isn't.  Also you lose potential energy when you burn fossil fuels since they are not atomized.  Gas is.  You could add carbide to the water.....That would give you acetelene gas, and you could fuel your car that way but carbide is expensive as well.

Water vapor doesn't do much to stop a fire.  Liquid water will stop a fire because there is a big gap in the amount of energy in liquid versus gaseous water.  Hence, when liquid water evaporates, it sucks up a lot of energy, and makes that energy unavailable for combustion.  It can also, I believe, work to smother the flame by keeping oxygen off the fuel source (but don't quote me on that).\n\nHowever, you must reconize that you've named elements, not molecules.  If you have those three elements in the form of water and carbon dioxide, you have nothing to burn.  If your elements are in the form of molecular oxygen and oil, then it will.  If you've got molecular oxygen, molecular hydrogen, and coal, then you bet will burn!

Put water under a vacuum. It will boil at room temperature. \n\nOr do you just want to create the illusion of steam? You could put dry ice in water. Then it will be could and appear to be steaming and boiling. And many people will think it is steaming.

My friends use BBQ lighting fluid. They have a performance company that specialises in use of poi and fire staffs. They are also students though so they use what is cheap and may not necessarily be the safest!\n\nThis is an excellent website (that my friends like) if you are interested in poi and other fire tricks. There's a gallery to see people in action.\nhttp://www.homeofpoi.com/\nThis is the same websites page on best (and safest) fuels.\nhttp://www.homeofpoi.com/articles/FireSafety.php

If enough moisture is evaporated from the food then it will eventually combust. I'd say a slice of pizza for 15 minutes should do it.

Paper?  It is not a liquid, and does not boil.  The ignition temperature of paper is 451 degrees F.

This is really cool, but is a bit involved.  Get ahold of something that roates, a record player would be best, but you could probably rig something up.  Then you need some metal screen, like the kind on your windows.  Saturate a piece of cotton (a few cotton balls) with a solution of barium chloride, or some other metal halide salt and isopropyl alcohol.  Light it on fire and put the screen over it and start the rotation.  First of all, the flame will be a cool color depending on what metal you chose and it will create a really cool cyclone effect as the air coming in through the screen is swirled.  Really nice effect!

Burn the paper and mix the carbon leftovers with the water. You should get some killer jailhouse results.

Not possible because three conditions have to be present for fire to occur.  Fuel, oxygen, and heat.  Remove any or all (in this case, heat due to the freezing) and the fire goes out.

Fire needs three things fuel, oxygen, and heat.  If you put sand over a fire it cuts off its oxygen.  If you put water over fire it cuts of its heat or energy.  If you reach in and take out all the fuel it will distingusih.  I wouldn't try the last one though lol.

It has been done before so don't go trying to burn anything you wouldn't want to get caught doing.LOL JK But yes it is possible to detect charred remains no matter what is used to fuel the fire.

Yes, a blowtorch WOULD ignite it. I don't know the temperature it burns at, but I've ignited it with a blowtorch before....

yes\nburn it on a low flame

Should think so.\n\nYou can take a pot of water and an intense laser with you to space (Combustion may not be your best bet, even if you are taking oxygen cylinders. It may get too unpredictable).\n\nOnce in space, direct the laser at the pot. In due time, it should 'boil'.\n\nWell actually, the behaviour of water at zero pressure is quite peculiar. It can be seen from the phase diagram that water skips the liquid state at low pressures, and exhibits sublimation. \nSo even if you manage to keep the water liquid until you ready it for boiling, the moment you expose it to space(meaning zero pressure) some of the water will immediately turn into vapour. The remaining mass, will, in the absence of any heat source, freeze. \n\nIf you do provide heating, it will obviously vapourize. \nThus, strictly speaking, it will not 'boil'.

1: put water in pan\n2: place pan of water on stove\n3: turn stove on high\n4: wait until water begins to boil\n5: boil for at least 15 minutes\n6: turn stove off and let water cool\n7: do what you wish with water\n remember--DO NOT  watch pot or the water will never boil
