A stream of burning vapor or gas, emitting light and heat; darting or streaming fire; a blaze; a fire.

To burn with a flame or blaze; to burn as gas emitted from bodies in combustion; to blaze.

This is a thin zone of combustion in which diffusion plays a dominant role. Flames in hydrocarbon fuels and air are less than 0.1 mm thick for stoichiometric mixtures.

A body or stream of gaseous material involved in the combustion process and emitting radiant energy at specific wavelength bands determined by the combustion chemistry of the fuel. In most cases, some portion of the emitted radiant energy is visible to the human eye.

A rapid gas phase combustion process characterised by self-propagation.

the process of combustion of inflammable materials producing heat and light and (often) smoke; "fire was one of our ancestors' first discoveries"

an exothermic, self-sustaining, oxidizing chemical reaction producing energy and glowing gas, of which a very small portion is plasma

a plasma that contains, among other things, a lot of hydroxyl (OH) free radicals

a region where a gas emits light because of the high temperature

a self-sustaining oxidizing chemical reaction producing energy and ionized gas ( plasma )

A flame plasma is formed when a flammable gas and atmospheric air are combined and combusted to form an intense blue flame. The surface of materials are made polar as species in the flame plasma affect the electron distribution and density on the surface. This polarization is made through oxidation. In addition, functional groups are deposited on the surface.

A product of combustion that produces light.

A flame is the product of a highly exothermic reaction (for example, combustion, a self-sustaining oxidation reaction). In other words, a flame is the visible (light emitting) part of a fire.
