Question

Explain the different colours of flame.

Answer 1

The temperature of a candle flame is indicated by its colour. The candle flame's inner heart is bright blue and has a temperature of about 1670 K ($1400^oC$). The brightest part of the blaze is there. Within the blaze, the hue changes from yellow to orange to red. The temperature will drop as you get farther away from the flame's core. The red component has a temperature of around 1070 K ($800^oC$).

Complete answer:
The temperature of a candle flame is indicated by its colour. The candle flame's inner heart is bright blue and has a temperature of about 1670 K ($1400^oC$).

The red component has a temperature of around 1070 K ($800^oC$).
A flame is divided into three regions. Innermost, lower, and outer zones, to be precise. The temperatures in each region are different. Each region is assigned a separate hue, which aids in recognising the temperatures in each zone.
The Outer Zone is the first of the three zones. It has a blue color to it.
The Middle Zone is the second of the three zones. It has a yellowish color to it.
Inner zone refers to the third zone. It has a grey or black colour to it.
The innermost part of the flame is the hottest.
Owing to the presence of unburned wax vapours, the inner region is black in colour.
The shades green, yellow, and red in a blaze have little to do with colour temperature. Flame colour is also influenced by gas excitations. Soot, which has a complex and varied structure of carbon compounds, is one of the most important constituents of a burning blaze. Because of the abundance of these materials, electrons can be excited to a nearly infinite number of quantum states. The energy released by each electron returning to its original state determines the colour of light emitted.
