For the most part, fire is a mixture of hot gases. Flames are the result of a chemical reaction, primarily between oxygen in air and a fuel, such as wood or propane. In addition to other products, the reaction produces carbon dioxide, steam, light, and heat. If the flame is hot enough, the gases are ionized and become yet another state of matter: plasma.

A flame is a mixture of GASES combining chemically and in some cases incanescent solid. A candle flame looks yellow because the of incandecent carbon. You can get this carbon out of the flame by simply placing a cold plate in contact with the flame and the carbon will be cooled and deposited on the plate as soot.

Gas

Neither, it's an active heat / chemical reaction. As an object reaches combustion temperature it begins to give off flammable gasses which are consumed by the flame, which adds heat to the burning object and sustains the combustion process. This reaction continues until the fuel source is consumed, oxygen is removed, or the temperature is lowered below that which can support the combustion process.

Well the flame is combustion. It burns methane a gas and produces carbon dioxide a gas. But it is really just energy.

"As a candle burns, it gives off molecules in the form of gases. Those molecules are in a very excited state, causing a breakdown of the chemical bonds that bind them together. This releases energy which you see as both light and heat from the flame. In other words, the flame is simply a column of very excited gases."

A flame is simply glowing gas and other combustible particles. It's not hot enough to be plasma

I agree with the fact its a light of energy and heat source caused by either a solid. liquid or gas burning.
