Hint: The candle is made up of the wax. When the burn-in presence of air produces the flame. The flame has a distinct zone such that the heat of the flame increases from the lower region to the upper region. These zones have a characteristic colour.
Complete step by step solution:
The candle is a source of light. The wax of the candle reacts with the oxygen in the air and produces carbon dioxide. The wax combusts to produce heat and light.
The substances which can vaporize on the burning are more likely to produce the flame. For example kerosene or the molten wax that is responsible for the producing flame.
The general structure of the flame is as shown below:
The candle has a different zone. These zones are created by considering the energy created or released as heat. The candles have a total of three zones. Each zone has a characteristic colour. These zones can help us to understand the temperatures of each zone. The three zones are as follows:
1) Outer zone
2) Middle zone
3) Inner zone
The outer zone is obtained due to the complete combustion of the substance. The outer zone is blue. This zone is considered as the hottest zone (high temperature) compared to another zone. This zone is the non-luminous part of the flame.
The middle zone of the candle flame is bright yellow. The middle zone is moderately hot and it is obtained due to the partial combustion of the fuel or the substance.
The third zone is also called the innermost zone. It is the least hot region. It cannot cause severe harm. This zone is reddish black. This zone appears black due to the presence of unburnt substance or wax vapours.
The candle has three-zone.
Hence, (B) is the correct option.
Note: Not every substance can produce the flame. The substances which cannot be vaporized during the burning cannot produce the flame. This substance chars only. There are two types of flames: luminous (which emits light) and non-luminous flame (do not emit light like the inner zone of flame)
