Why won’t Candles explode after burning?
Why won’t liquid wax or liquid gasoline catch fire, and what does the wick do to allow the liquid wax to catch fire?
We know that it takes a lighted match to light a candle. The wick then carries liquid candle wax upward into the wick.
What happens in the wick that allows the liquid wax to be ignited?
It doesn’t have to be right. It just has to be testable. Liquids cannot burn. Liquids have to evaporate into the air as a gas in order to catch fire.
When the liquid wax climbs the wick through capillary action, the heat of the flame evaporates the liquid wax into the air where the wax mixes
with oxygen and catches fire capable of lightening but do not explode. Using candles is not dangerous but it just doesn’t need to be left unattended.
