Question

The yellow-orange glow of the soot in a flame is characteristic of temperature near.

A) 500°C
B) 1000°C
C) 1500°C
D) 2000°C

Answer 1

The yellow-orange glow of the soot in a flame is characteristic of a temperature near 1500°C. This color is caused by the thermal radiation emitted by the hot particles.

Step-by-step explanation:

The yellow-orange glow of the soot in a flame is characteristic of a temperature near 1500°C. At this temperature, the soot particles in the flame are heated enough to emit light with a yellow-orange color. This color is caused by the thermal radiation emitted by the hot particles.
