tempatures of the flame?

A candle flame reaches 205 degrees centgrade.\n\nThe cutting torch you referred to is an oxyacetylene torch that burns ethyne (acetylene) in pure oxygen, producing a high-temperature flame (3,000°C/5,400°F). It is widely used in welding to fuse metals. In the cutting torch, a jet of oxygen burns through metal already melted by the flame.\n\nThe blue part of the flame is the hottest as this has the most oxygen.

I'm not sure about your question, but.....\nThink of fire as a live animal. It needs heat, food, and oxygen. If you take away one of the three, the fire will die. Fire can double in size every eight seconds given enough 'food' and air.  The tip of the flame does not evaporate.

everything can burn at a high enough temp\nthey melt before burning because of physical properties\nit is part of the solid-liquid-gas chain\n***get smarter, dude, it is possible, have you ever thrown water on a fire that was 50,000 degrees?

37º\n\nbeyond 38º it's a fever\n\nhope that helps

what's the heat source?

I've never heard the term "flame point" specifically.  I'm assuming it's the same as the flash point.  The flash point is the temperature at which the vapor pressure of a fuel is high enough to be ignited when in atmospheric air.  Gasoline has a flash point of -40 deg, so there is enough gasoline vapor to be ignitable at any temperature above that.  Diesel fuel has a flash point of well over 100 deg F, meaning that there is not enough Diesel vapor to be ignitable at room temperature.

Fire is supposed to be a plasma and/or energy. It goes up because the expanded gasses in the flame "weigh" less than cool air (like a hot air baloon). It doesnt have a shape. it adapts to the shape of the container. It looks like a drop because of the hot air "pulling" it up.

What we usually called fire or flames is actually the combination of the brilliant glow and large amount of heat released by hot gases that are the result of the combustion of a fuel. This fuel can be any combustible material. Since that combustible could be any substance that can be burned, then there is not specific equation for every "fire" but there could be one general equation... \n\nThere are three things needed to have fire, the process of combustion of inflammable materials producing heat and light and (often) smoke,\n\n1.- Heat\n2.- Fuel\n3.- Oxygen\n\nSo the equation could be:\n\na Fuel + b Oxygen + Heat -----> c Gases + d Ashes + Fire\n\na, b, c and d values would depend on the nature of the fuel and the oxygen available.\n\nOxygen, 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.\n\n:-)

The air surrounding the flame is heated up. \n\nThe density of hot air is less and hot air goes up, the cooler light air fills that space. \n\nHence the shape of the flame is maintained.

The melting point is 1068 kelvin and 795 celsius. The boiling point is 3633 kelvin and 3360 celsius.

Boiling point: sublimes at ca. 1185°C (2165°F)

Hot air is less dense than cold air.\nThe air around the fire is very hot and bends light like a lens. \nAs the fire is not uniform, the air heats and cools with the flames. This causes light to bend in different degrees. Your eyes follow these changes the objects behind the fire seems to be shimmering.

It depends on what is being burned.  Ordinary book paper, for instance, is 451°F.  Different woods would burn at different temperatures, and also depending on the water content the temp would be different.  You need to specify.

Condesates formed under high temp. and pressure can reach flash points suddenly. They usually combust with a flame whose characteristics depends on the material.\n\nIt can be used as reaction indicators or flashes.
