The ember of a cigarette stays lit longer because it contains a higher concentration of heat-producing chemicals. These chemicals are released when the tobacco is burned, and they help sustain the ember's heat and combustion.
The ember of a cigarette is composed of partially burned tobacco, ash, and other byproducts of combustion. The non-burning tobacco, on the other hand, is mainly composed of dried plant material and contains less heat-producing chemicals.
The ember of a cigarette produces more smoke because it contains a higher concentration of heat-producing chemicals, which leads to more efficient combustion and the release of more smoke.
The ember of a cigarette continues to glow due to the presence of smoldering particles and residual heat-producing chemicals. These particles can continue to smolder and produce smoke even when not being actively smoked.
The ember of a cigarette is an essential part of the burning process, as it provides a sustained source of heat and combustion. Without the ember, the tobacco would not continue to burn and produce smoke. It also helps to ignite and sustain the burning of new tobacco as it is drawn into the cigarette during smoking.
