Zones in a candle flame The interior of the luminous zone can be much hotter, beyond 1,500 °C (2,730 °F). [3]Color and temperature of a flame are dependent on the type of fuel involved in the combustion, for example, when a lighter is held to a candle.
Color temperature is a parameter describing the color of a visible light source by comparing it to the color of ... Candle flame, sunset/sunrise: 2400 K Standard ...
The constant-pressure adiabatic flame temperature of such substances in air is in a relatively narrow range around 1,950 °C (2,220 K; 3,540 °F). [citation needed] This is mostly because the heat of combustion of these compounds is roughly proportional to the amount of oxygen consumed, which proportionally increases the amount of air that has ...
The color of the flames also generally depends on temperature and oxygen fed; see flame colors. [5] The procedure uses different solvents and flames to view the test flame through a cobalt blue glass or didymium glass to filter the interfering light of contaminants such as sodium. [12] Flame tests are subject of a number of limitations.
Colored fire. A campfire burning with blue and green flame colorants. Different colors of natural flame from a bunsen burner, without additives. Colored fire is a common pyrotechnic effect used in stage productions, fireworks and by fire performers the world over. Generally, the color of a flame may be red, orange, blue, yellow, or white, and ...
Fire. A burning candle. Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [1][a] At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire.
Reducing flame. A reducing flame is a flame with insufficient oxygen. It has an opaque yellow or orange color due to carbon or hydrocarbons [3] which bind with (or reduce) the oxygen contained in the materials the flame processes. [2] The flame is also called carburizing flame, since it tends to introduce carbon soot into the molten metal.
The color of the flame is dependent on the metal cation; the anion of the salt has very little direct influence. The anions however influence the flame temperature, both by increasing it (e.g. nitrates, chlorates) and decreasing it (e.g. carbonates, oxalates), indirectly influencing the flame brightness and brilliancy.
