How Does a Candle Burn for Hours?

A candle burns for hours because it keeps getting more fuel from the wax. When you light a candle, the flame melts the wax near the wick, and that liquid wax travels up to the flame. The flame turns the wax into gas, which then burns, keeping the flame going. It’s like having a never-ending snack for the fire!

Examples

A tiny candle can burn for hours because it keeps getting more fuel from the wax, just like a person eating a big bag of chips one snack at a time.
The flame doesn’t die when you light a candle, instead, the melted wax keeps rising up to feed the fire.
Even though the wick is small, the wax has a lot of energy stored in it, which makes the flame last for hours.
