What is the stem of a candle made of and are there any special effects that occur when it melts?
I have been observing a lit candle, and all I see is wax melting to liquid form and when the candle is blown, it turns back to wax. But I dont see any...
I have been observing a lit candle, and all I see is wax melting to liquid form and when the candle is blown, it turns back to wax. But I dont see any ‘Chemical properties’.
also is the stem made of only cloth and wax?Or are there other substances such as fuel?
The center of a candle is some rope. The wax turns liquid because of the heat of the flame (just like ice melts). The wax is then absorbed by the rope (which also isn’t a chemical reaction), and is burnt at the tip of the rope.
The fire removes the wax from the tip, but the removed wax is immediately replenished by the wax being absorbed. Because of that, the candle keeps on burning. The wax is the fuel, and there is no need for other chemicals.
