Question

Why it is more hotter for same distance over the top of a candle than it in the side of the flame?

Answer 1

OK, now lets move upwards to the top of the dark area inside the flame. ... Actually, the hottest part of the candle flame is the blue part, at 1670 degrees F (1400 C.) That is where the flame has the most oxygen and you are getting complete combustion. The reddish partis the coolest part, about 1070 F (800C).
