Answer 2

Answer:

hey mate

here's ur answer

I don't know about 4 and. sorry

Explanation:

3 = dark zone

In this region particals of carbon are present that are not burnt...

this is the coldest zone in the flame due to the presence of wax vapour...Also, known as the inner most zone or the zone of no combustion....this area does not come in contact with oxygen and the wax does not burn...

4=blue zone

if u observe carefully,, u will notice that a very small area, near the base of the flame is blue... since oxygen is available to the wax vapour in that region, there is almost complete combustion of carbon particles

u can search the digram on Google

it's not taking more pictures

hope this will help u

good byeee
