What is the lowest temperature for fire?
A cool 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..
Can Ice put out a fire?
That’s one way to put a fire out. … The reason ice is not ideal for fighting fire is that the goal of water is to turn it to steam and let that do the cooling. We don’t deprive oxygen by introducing water into a fire.
Who is most likely to start a fire deliberately?
Deliberate fires are often set by children and young people….Examples of which may include:An usual fascination with fire.Boredom.Unexplained fires within the home.Burn holes in carpets beds or furniture.
How hot is fire from a lighter?
3,590.6 degrees FahrenheitBic lighter flames burn surprisingly hot. 3,590.6 degrees Fahrenheit actually. This is assuming the lighter has butane in It.
At what temperature does cardboard spontaneously combust?
Corrugated board is combustible and should therefore be protected from flying sparks. Smoking must be strictly prohibited. The fire point is 258°C, the ignition temperature 427°C. When stacked, it has a tendency to heat-induced spontaneous combustion.
What happens if you put dry ice in fire?
Tiny dry ice pellets can be used to fight fire by both cooling fuel and suffocating the fire by excluding oxygen. The extreme temperature of dry ice can cause viscoelastic materials to change to glass phase.
Which extinguishes fire more quickly hot or cold water?
The process of fire extinguishing involves absorption of heat. Absorption of heat in converting hot water to steam is more than heat absorbed in heating cold water to the boiling temperature. Hence, hot water extinguishes fire more quickly than cold water.
At what temperature can a fire start?

Is fire cold or hot?
D. 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.
How hot is violet fire?
Violet light can sometimes glow at around 71,000 degrees Farenheit. For reference our sun burns at 8,500 degrees Fahrenheit, glowing in white and yellow!
What heat transfer happens when you burn your finger by touching a fire?
If you stoke your log fire in the fireplace with a poker and leave the poker in the fire, it will become very hot. A heat exchanger uses a hot fluid to conduct heat to a cooler fluid without the two touching. If you touch a hot stove, heat will be conducted to your finger and your skin will burn. Sand can conduct heat.
Why can you feel the heat from a fire when sat near it?
This light, being a wave, carries energy, so it can move from one place to another without requiring a medium. When this light reaches you, part of the energy of the wave gets converted back into heat, which is why you feel warm sitting beside a campfire.
Is there black fire?
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.
Does boiling water put out fire?
Remember, water takes heat from the fire, it cools it. … Although it is true that technically cold water will put out a fire faster than hot water, most of the cooling effect comes from changing the water into steam, not from raising the temperature of the water.
Is green fire hotter than blue?
A green flame is just as hot as any other kind of flame, except it has color added to it, due to the presence of a “contaminant”. The contaminant may be copper, barium, thallium, barium or Niobium, in order for the flame to show a green color.
Can heat cause a fire?
FUEL, which can be a solid, a liquid or a gas. Once there is a heat source to cause ignition and a sufficient amount of fuel and oxygen present the fire will continue to burn. As the fire burns, large amounts of heat are produced. … This transfer of heat causes the fire to grow and to spread to other areas.
What is the hottest color for fire?
The inner core of the candle flame is light blue, with a temperature of around 1800 K (1500 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange, and finally red. The further you get from the center of the flame, the lower the temperature will be.
Is purple fire hotter than blue fire?
As things heat up and combustion becomes more complete, flames turn from red to orange, yellow and blue. And purple color is combination of red & blue color it means that blue fire is more hotter than purple fire. … At hotter temperatures, the flame color moves into the blue-violet end of the visible spectrum.
Why is hot fire blue?
The color blue indicates a temperature even hotter than white. … 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.
What is the highest temperature a fire can reach?
An average surface fire on the forest floor might have flames reaching 1 metre in height and can reach temperatures of 800°C (1,472°F) or more. Under extreme conditions a fire can give off 10,000 kilowatts or more per metre of fire front.
Is water stronger than fire?
Water is more powerful with life and giving back in my opinion and many others because, though it can kill, it houses many creatures and almost everything in the world needs it to survive. … Fire is seen as more deadly, although it also helps with life and living, though a bit less than water.
Is Blue fire hotter than the sun?
Flames look yellow when they have have particles of unburnt carbon in them, and they look blue when there is no unburnt carbon present. The amount of unburnt carbon decreases as the flame gets hotter, so blue flames are indeed (usually) hotter than yellow flames. … The Sun is not a flame as nothing is burning in it.
How is the heat from a fire transmitted?
A fire spreads by transferring heat energy in three ways: Radiation, Convection, and Conduction. Radiation refers to the emission of energy in rays or waves. … This is the reason that when facing the fire, only the front is warmed. The backside is not warmed until the person turns around.
Can cold put out a fire?
Freezing temperatures won’t stop fires from spreading, but it will change what happens when firefighters arrive on the scene.
