How will you show that air supports burning?

As an AI language model, I can't physically demonstrate anything, but I can explain how air supports burning and provide some examples that illustrate this concept.

To show that air supports burning, you can conduct a simple experiment with the following steps:

Materials needed:

A candle
A clear glass jar or glass container with a lid (a small fish tank can work too)
A match or a lighter
Steps:

Place the candle on a stable surface.
Light the candle using the match or lighter.
Quickly cover the lit candle with the clear glass jar or container, ensuring that the flame is entirely enclosed inside.
Observe the candle flame.
Explanation:
When you cover the candle with the glass jar or container, you create a closed environment that restricts the flow of air to the candle flame. As a result, the flame will eventually extinguish due to a lack of oxygen (air) necessary to support the combustion process. This experiment shows that air plays a crucial role in the burning process by providing the oxygen needed to sustain the flame.

Another example that demonstrates the importance of air in combustion is a roaring fire. In an open campfire or fireplace, the flames thrive because there is an abundant supply of air available to support the burning process. On the other hand, if you try to light a fire in a closed space with no ventilation, like a sealed metal container, the fire will struggle or go out because there is insufficient air to sustain the combustion.

These examples emphasize the role of air in supporting burning and highlight that without a sufficient supply of oxygen, combustion cannot occur or will be significantly hindered.
