Final answer:
A visible flame is produced in the flaming mode of combustion, where fuel vaporizes and reacts with oxygen. An example is a lit candle. Therefore, correct answer is option B.
Step-by-step explanation:
Flaming combustion, a captivating interplay of fuel and oxygen, manifests as a visible flame aglow with heat and light. This dynamic process unfolds when a fuel source engages in combustion in the presence of oxygen. In the flaming mode, the fuel undergoes vaporization, an essential precursor to a fiery spectacle.
An exemplar of this phenomenon is the ignition of a candle, where the wax transforms through the heat emanating from the flame. As the wax vaporizes, it engages in a lively dance with oxygen molecules in the surrounding air, sparking a combustion reaction. This intricate chemistry releases energy in the form of heat and light, unveiling the mesmerizing glow of a visible flame.
The dance of molecules in flaming combustion paints a vivid tableau, showcasing the transformative power of chemical reactions and the allure of the elemental interplay between fuel and oxygen.
