1. Candle Experiment: Cover a lit candle with a jar; the flame diminishes due to lack of oxygen inside.
2. Flame Extinguishment: Proves air supports burning; oxygen from air is necessary for combustion.
3. Reignition: Removing the jar and reigniting the candle confirms air’s role in supporting burning.
Place a burning candle upright in a tray having water. Cover it with a glass jar. Water will make it air-tight. During burning, oxygen is consumed and carbon-dioxide is released. After sometime no oxygen is left inside the jar and flame goes out. It shows air support burning.
