What is Air?
Air is a mixture of gases that envelops the Earth’s surface and extends outward into space. It primarily consists of nitrogen (about 78%) and oxygen (about 21%), with trace amounts of other gases such as argon, carbon dioxide, and water vapour. Additionally, it contains suspended particles such as dust, pollen, and pollutants.
Air is vital for sustaining life, as oxygen is essential for respiration in most organisms. It also plays a crucial role in weather patterns, climate regulation, and the transmission of sound and light. Furthermore, air serves as a medium for combustion and supports various industrial processes. Overall, air is a dynamic and essential component of Earth’s atmosphere, with diverse functions and properties.
Air for Breathing and Combustion
Air is one of the elements that sustains life on Earth. Air serves two crucial functions – sustaining life through respiration and fueling combustion processes. The air around us makes up the Earth’s atmosphere, which extends about 11 kilometres high. As we get closer to the ground, the air becomes thicker because of gravity.
This air has the right mix of gases and pressure to support life. High in the atmosphere, the ozone layer acts like a shield which protects us from harmful rays from space. In this article, we will read about how air is used in respiration and combustion.
