Maybe you’ve thought about this question while looking at a burning candle: Where does all of its material disappear as the candle shrinks as it burns?
When you look at a burning candle, you may think it appears to be disappearing, but much more than what you see is occurring.
This “lost” situation is something we can explain thanks to science. chemical reaction It actually stands. Let’s get into the details.
Candle is a kind of fuel.
A candle consists of two parts: wick and wax (soy wax, paraffin wax, beeswax or another type of wax…). Regardless of its type, wax contains hydrogen and carbon atoms; well Contains hydrocarbons.
We can think of the candle itself as fuel, but even when exposed directly to fire It does not burn easily on its own without a wick.
When the wick is lit, the heat of the flame begins to melt the wax at the base of the wick and draws the liquid wax into the flame. The intense heat of the candle flame causes the melted wax in the wick to evaporates and turns into flammable gas vapor It helps.
The wax, which reacts with oxygen in the air and evaporates, catches fire and releases the following:
- Energy, light and heat
- Smoke
- Carbon dioxide
- water particles
To summarize…
The wax is transformed by a combustion reaction that involves the heat of the flame as well as the presence of oxygen and fuel. Like this solid wax turns into carbon dioxide gas and water vapor is transforming.
We can also say: the heat of the flame breaks the hydrocarbons into separate hydrogen and oxygen molecules wax first from solid to liquid, then from liquid to gas It transforms.
