We all know about the importance of air in our lives because this is the main reason for life on Earth. Without its presence, life would be impossible, and other planets in our Solar system are evidence of that. Hence, air is a natural advantage that supports life on Earth. What are the uses of air in different areas of our life? We present you 10 uses of air in daily life.
What is air?
Air is an invisible form of matter that flows freely and is in the gaseous state. Scientists described the composition of air and its main properties in such sciences like physics and chemistry. Many gases such as nitrogen, oxygen are present in air in different proportions.
In addition, it also contains gases such as hydrogen, carbon dioxide, carbon monoxide. Air is naturally clean and safe for human and animals, but due to industrialization pollution of the air is increasing which is unsafe for breathing. Therefore, to use clean air and to maintain a dust-free breathing, variety of air filters are widely used.
4 uses of air
Air is a significant supplier of energy: all living plants and animals depend on oxygen to generate valuable energy. Body cells take oxygen from the blood and produce energy after consuming food in the form of ATP. This biochemical generation of ATP is essential to maintain life on the Earth. So, this is one of the uses of air.
Air is a conducting medium for sound: we are able to hear the sound of speech or noise etc only when there is air around us. This happens due to the fact that air is a good sound conductor. Without air, we won't be able to hear anything and won't be able to produce the sounds.
The water cycle occurs with the help of the air: water cycle is a phenomenon of water from the soil, the oceans and seas evaporating due to the heat of the sun and forming clouds. These clouds move towards the land surface, and they are cooled by air and rain. This rainwater once again reaches the sea and ocean.
The pollination of agricultural crops also happens due to the air: plants produce male gametes in pollen grains. These pollen grains move from the male flower to the female flower and combine with female gametes. And that exactly what is called pollination. This may occur in flowers growing on the same plant or between remote plants with the help of wind power.
