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.

There are three zones in flame, viz. outer zone, middle zone and inner zone. Outer Zone: This zone is blue in colour. It is the hottest part of the flame, because complete combustion takes place in this zone.

But wait, there's more: With a high natural ignition point of about 1,382 degrees Fahrenheit, wool is fire-resistant. And unlike nylon and polyester, wool does not drip or melt when it does catch fire.

Fire is hot because the conversion of the weak double bond in molecular oxygen, O2, to the stronger bonds in the combustion products carbon dioxide and water releases energy (418 kJ per 32 g of O2); the bond energies of the fuel play only a minor role here.

Campfires can reach an average temperature of about 930°F (498.9°C), but this varies depending on the size of the fire. Medium sized fires can reach 1,112°F, while large fires (as big as those huge bonfires that you see on TV during beach parties) can reach up to 2,012°F.

['Ignition: Fuel, oxygen and heat join together in a sustained chemical reaction. ... ', 'Growth: With the initial flame as a heat source, additional fuel ignites. ... ', 'Fully developed: Fire has spread over much if not all the available fuel; temperatures reach their peak, resulting in heat damage.']

My guess is, fuel + air ignites optimally at some particular air temperature. 175 to 180 degrees will give optimal economy that I've seen.

Idealna temperatura do smażenia frytek to 180-190 stopni C, czyli poniżej punktu dymienia wysokogatunkowej oliwy extra virgin. Zatem tak, możesz usmażyć na oliwie frytki czy używać jej do głębokiego smażenia innych potraw.

What is the change in enthalpy for the production of 1.00 mol SnO? 1Sn + 1SnO2 + 92 kJ → 2SnO (note: The reaction is endothermic so ∆H = +92 kJ) 7.

A material is considered combustible if it has a flash point higher than 37.8 ºC and below 93.3 ºC. Flammable and combustible materials will generate vapours when exposed to a temperature at, or above, its flash point, which can easily ignite when exposed to an ignition source.

The gases burn and increase the temperature of the wood to about 600 degrees Celsius (1,112 degrees Fahrenheit). When the wood has released all its gases, it leaves charcoal and ashes. Charcoal burns at temperatures exceeding 1,100 degrees Celsius (2,012 degrees Fahrenheit).
