What are the different flames on a Bunsen burner?

It burns with a pale blue flame, the primary flame, seen as a small inner cone, and a secondary, almost colourless flame, seen as a larger, outer cone, which results when the remaining gas is completely oxidized by the surrounding air.

What are the 3 types of flame produced by the Bunsen burner?

Three types of flames are obvious when adjusting the air and gas mixture. The yellow flame, commonly known as the safety flame, is the coolest flame at almost 300 degrees. The blue flame, can reach temperatures of approximately 500 oC and is almost invisible in a bright room.

What are the different region of the flame?

Three zones, for example, are apparent in the Bunsen burner flame: an inner zone of unburned gas; a middle zone called the reduction zone or reducing flame, since there the supply of oxygen is deficient and the oxygen is therefore removed from an oxide placed in it; and an outer, or oxidizing, zone.

What is the flame called on a Bunsen burner?

What color is a flame?

The inner core of the candle flame is light blue, with a temperature of around 1670 K (1400 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange, and finally red. The further you reach from the center of the flame, the lower the temperature will be.

Which flame is used for cutting operation?
