Describe the experiment that demonstrates that air supports burning. Mention the setup, observation, and scientific principle involved.
1
Place a lit candle under a jar until it extinguishes, demonstrating oxygen's role in combustion.
2
Light a fire in an open field and observe its spread, demonstrating wind's role in fire propagation.
3
Burn different materials to see which burns fastest, analyzing combustion rates.
4
Observe the color of flames in different gases, assessing combustion efficiency.
