Fire is an event, not a substance. When wood is heated, or any other fuel for that matter, vapours are released. These quickly ignite in the air. This results in an explosion of gas which further heats the fuel.
A house fire will double its size in a minute if the conditions are stable. This includes oxygen, heat and fuel.
The only place where you can get the perfect conditions for fire to burn is on Earth. There is no other place that has sufficient oxygen. For details on a Fire Risk Assessment Northamptonshire, contact https://isefireproducts.co.uk/fire-risk-assessments/northamptonshire
What colour the fire burns depends on how much oxygen is present. Low oxygen fires will burn a yellowish-orange, while high oxygen fires are blue.
The candle will burn blue in the lower part of the flame because this is the place where the oxygen enters. As the flame gets higher, it turns yellow because the fumes begin to suffocate the air supply.
Water can be made by fire. You don’t believe this? You can actually see water vapour condensing on a metal spoon if you carefully hold it over the candle. Hydrogen is found in the wax of a candle. This hydrogen bonds with oxygen to form H2O. The same thing happens when you see water escaping from your exhaust pipe.
Fires have been burning in the natural world for many years. It is believed that a coal seam has been burning in Australia for over 500,000 years.
Mirrors and concentrated sun were used to start fires in ancient Greece. The Olympic Torch is lit using a parabolic reflector that concentrates sunlight.
The Great Fire of London of 1666 destroyed 80% of London. The fire was devastating, but it had an unexpected benefit: It killed the bubonic disease that had caused 65,000 deaths the previous year. It killed rats and fleas which carried the plague-causing bacteria.
