Can fire *be* burned? Though as a wall built partly of flammable material I wish fire could be burned, it can't. Fire is just the light and heat resulting from oxidation of fuel; there is nothing in fire to oxidize, because fire itself isn't a substance it's a process.
Fires burn only when all that atomic shuffling releases enough energy to keep the oxidation going in a sustained chain reaction. More atoms released from the fuel combine with nearby oxygen. That releases more energy, which releases more atoms. This heats the oxygen — and so on.
“Fire is hot because thermal energy (heat) is released when chemical bonds are broken and formed during a combustion reaction. Combustion turns fuel and oxygen into carbon dioxide and water. … Both light and heat are released as energy.” So water is not wet and fire is hot.
The actual flames of the fire are the release of some of the heat energy as light. These components have led to the development of the 'fire triangle' of fuel, oxygen and heat. Remove any one of these and fire cannot sustain itself.
Fire is the visible effect of the process of combustion – a special type of chemical reaction. It occurs between oxygen in the air and some sort of fuel. The products from the chemical reaction are completely different from the starting material.

What is fire made of?
Oxygen, heat, and fuel are frequently referred to as the "fire triangle." Add in the fourth element, the chemical reaction, and you actually have a fire "tetrahedron." The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.
Fire occurs whenever combustible fuel in the presence of oxygen at an extremely high temperature becomes gas. Flames are the visual indicator of the heated gas. Fire can also occur from lower-temperature sources. Over time, combustible materials such as smoldering embers can reach their ignition temperature.
Short answer: Water is formed as a result of the combustion of hydrogen. In simple words, water is what you get when you burn hydrogen. So, water doesn't burn because, in a way, it has already burned.
A cool flame or invisible flame is a flame having maximal temperature below about 400 °C (752 °F). It is usually produced in a chemical reaction of a certain fuel-air mixture. Contrary to conventional flame, the reaction is not vigorous and releases very little heat, light, and carbon dioxide.
Nothing can last forever – including a fire. Eventually, the fuel source will be exhausted and the heat will radiate away. Even so, the truth about the world's longest burning fires is so strange that it's almost unbelievable. Under the right conditions, fires can burn throughout entire ages of history.
If we're using it as an adjective (definition: covered or saturated with water or another liquid), then lava is a liquid state so it therefore it's wet. But nothing touched by lava is left damp or moist, which means that you can't really use wet as a verb to describe lava.
Wet air is air that contains the highest level of water vapor. In general, air contains some moisture or water vapor, regardless of the temperature and air pressure.
Can Blood Catch On Fire? The short answer is 'no'. Of course, blood is not flammable. This is due to 60% of the liquid substance being made up of plasma, of which a huge portion is made up of water (around 92%).
The buildup of decaying organic matter on the ground is fuel for wildfires. Without periodic fire to clear this out, a naturally occurring fire may grow and move quickly, doing much more damage that a prescribed burn—and without its safety parameters.
People sometimes think fire is living because it consumes and uses energy, requires oxygen, and moves through the environment. Fire is actually non-living.
False. First of all, staring into a fire for two to three minutes would not allow the contact lens to reach its melting point unless the person was actually in the fire, at which point they would experience severe life-threatening burns to the body and eyes.
Blue flames usually appear at a temperature between 2,600º F and 3,000º F. Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood. When natural gas is ignited in a stove burner, the gases quickly burn at a very high temperature, yielding mainly blue flames.
Always simmer, if you boil milk too hard or too fast it will scorch and burn if not stirred. As soon as it boils remove from the heat and keep stirring.
Air will never spontaneously combust, nor can it be made to burn non-spontaneously. Air is mostly nitrogen, which is not flammable. Nitrogen is also non-reactive in general, so it doesn't support the combustion of other materials, either.
The controlled use of fire was likely an invention of our ancestor Homo erectus during the Early Stone Age (or Lower Paleolithic). The earliest evidence of fire associated with humans comes from Oldowan hominid sites in the Lake Turkana region of Kenya.
The oldest unequivocal evidence, found at Israel's Qesem Cave, dates back 300,000 to 400,000 years, associating the earliest control of fire with Homo sapiens and Neanderthals. Now, however, an international team of archaeologists has unearthed what appear to be traces of campfires that flickered 1 million years ago.
The hottest flame ever produced was at 4990° Celsius. This fire was formed using dicyanoacetylene as fuel and ozone as the oxidizer. Cool fire may also be made. For example, a flame around 120° Celsius may be formed using a regulated air-fuel mixture.
