Question

Why does the flame of candles rise of to a good height after burning? ​

Answer 1

Answer:

When a candle burns, the flame heats the nearby air and starts to rise. As this warm air moves up, cooler air and oxygen rush in at the bottom of the flame to replace it. When that cooler air is heated, it too rises up and is replaced by cooler air at the base of the flame.

at its peak, there is insufficient incoming ambient air (and hence oxygen) to burn, and its length is reduced. A smaller flame allows more ambient air which causes the flame height to increase.
