Challenge Question 4: The Candle Experiment Logic - For Air and Atmosphere
🕯️ Challenge 4: The Starving Flame
When we put a glass tumbler over a candle, it goes out. Does it go out because it "ran out" of oxygen, or because the Carbon Dioxide "poisoned" the flame? Use the chemical equation for combustion to explain.
🌟 Sample Ideal Answer:
The flame goes out primarily because it ran out of Oxygen. According to the combustion equation (Fuel + Oxygen → CO2 + Water + Heat), Oxygen is a reactant—meaning it is a necessary "ingredient" for the fire to exist. While Carbon Dioxide is produced, the flame cannot continue to burn once the limited supply of Oxygen inside the glass is consumed. Without Oxygen, the chemical reaction simply stops!
