Question

Which zone of the candle flame gives us light? Why do you think so?

Answer 1

The middle zone also known as luminous zone which is moderately hot with limited oxygen supply so these zone flames gives us light with yellow colour

Answer 2

Answer:

Luminous zone

Explanation:

This zone is the zone of partial or incomplete combustion. It looks yellowish colour. Here the supply of oxygen reduces and the carbon particles leave the flame as smoke and soot. Luminous zone consists of a partial combustion with liberation of heat in large amount and thus light is emitted.
