1.	3. Why does a burning candle get shorter?
Answer» As the fuel (wax) is melted and burned, the candle becomes shorter. PORTIONS of the wick that are not emitting VAPORIZED fuel are consumed in the flame. ... This ensures that the end of the wick GETS oxygen and is then consumed by fire—a self-trimming wick.
