Is it possible to freeze flames

But I think the answer is yes. IIRC, fire requires fuel, heat and oxygen, and the removal of any one is enough to extinguish it.

Here we go: The Fire Triangle. Looks like the best way of removing heat is, um, dousng the fire with water. So if a match was frozen, would it refuse to light? Or if you brought a burning candle from one room to another that was identical in all aspects except temperature, would it burn out more quickly? For a fire already started, sounds like you need a radical drop in temp, not just the onset of a cold snap.

Back in grad school we hosted a superbowl party one January in Wisconsin. We knew from a few weeks earlier that the charcoal grill just would not stay lit when it was bone-ass cold outside. But it is still hot enough to burn you. Class B Fires — Extinguish by Depleting Oxygen Flammable liquids include petroleum-based oils or paint, tars, alcohol, oils, solvents, gasoline and kerosene.

Flames emits light and heat, so it seems impossible to make black fire. However, you actually can make black fire by controlling the wavelengths of absorbed and emitted light. Can it be too cold to make a fire? Category: home and garden home appliances. The heat from the flame vaporizes the fuel which then mixes with the oxidizer and burns.

For some fuels if the temperature is low enough, not enough will vaporize to sustain the fire and it will go out. Does temperature affect fire? At what temperature does cardboard spontaneously combust? Does fire burn faster in cold air? What quenches a fire by cooling it?

Can heat alone cause fire? Is fire always the same temperature? Can air put out fire? At what degree does fire start? What substance puts fire out the fastest? Does boiling water put out fire? For others, everything depends on the level of ionization, and in the case of fire, it would not be so high. So partial plasma? Semi plasma? It all starts with an electrode, which reaches tens of thousands of volts.

The potential is so high that the gas around the electrode is ionized. This requires a gas that is easily ionized and that has a higher thermal conductivity. But even if you take the conventional view of the flow of time, motion does not stop at absolute zero. This is because quantum systems exhibit zero point energy, so their energy remains non-zero even when the temperature is absolute zero. So the answer would be however long you can go without oxygen.

The reason has to do with the amount of work necessary to remove heat from a substance, which increases substantially the colder you try to go. To reach zero kelvins, you would require an infinite amount of work.

These black holes are dark most of the time, but when their gravity pulls in nearby stars and gas, they flare into intense activity and pump out a huge amount of radiation.
