⚛️Air is not a single entity, but a mixture of different gases in varying percentages.
🔥Oxygen is the part of air that supports combustion and is required for burning.
🕯️The experiment with candles and glass vessels demonstrates the presence of oxygen in air.
💨Nitrogen constitutes 80% of air and is the largest component in the mixture.
🧪Besides oxygen and nitrogen, air also contains gases such as carbon dioxide and inert gases.
What is air made of?
