We all know about the importance of air in our lives because it is the main reason for life on Earth. Without its presence, life would be impossible, and other planets in our Solar system are the evidence of that. Hence, it is a natural resource that supports life on Earth. What are the uses of air in different areas of our life?
Air is used like all other natural resources. In our daily life, it is impossible to survive without it, and there are different things it can be beneficial for. You can check out some uses of air pictures and descriptions below.
What is air?
Air is an invisible form of matter that flows freely and is in the gaseous state. Scientists describe the composition of air and its main properties in such sciences like physics and chemistry. Many gases such as nitrogen and oxygen are present in the air in different proportions.
In addition, it also contains gases such as hydrogen, carbon dioxide, and carbon monoxide. It is naturally clean and safe for humans and animals, but due to industrialization, it is increasingly getting polluted, making it unsafe for breathing. Therefore, to maintain dust-free air, a variety of filters are widely used.
We present to you 10 uses of air in daily life.
10 uses of air
Air is important for the breathing of all living things on Earth. It provides oxidation processes that supply the body with the necessary energy. In addition, it has the widest application in various fields of industry. Here are some common uses of air with pictures.
- It 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.
- It is a conducting medium for sound: we can hear the sound of speech or noise, etc. only when there is the air around us. It happens because the wind is a good sound conductor. Without a medium, we will not be able to hear anything and won't be able to produce the sounds.
- It is an important part of the water cycle: the 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 wind and rain. This rainwater once again reaches the sea and ocean.
- It is responsible for the pollination of crops: plants produce male gametes in pollen grains. These pollen grains move from the male flower to the female flower and combine with female gametes, which is called pollination. This may occur in flowers growing on the same plant or between remote plants with the help of wind power.
- It keeps the balance of the temperature on the Earth's surface when it's summer. When the sun strongly heats the Earth's surface, the surface temperature of the ground is growing rapidly, but it grows slowly on the surface of the ocean or sea (this is because a solid substance is heated faster than liquid water). Thus, the air that is warmed at the Earth's surface rises up, and the cold one from the sea surface transfers to the surface of the ground which minimizes the temperature rise.
- It helps in drying (moisture balance): the ground being wet from the rain dries due to air. On a wet surface, it is very moist. Thus, the moist layers are replaced by less humid or dry layers of air. The new dry layer on the surface absorbs moisture from the wet surface, and the cycle continues until the surface is dry.
- It also helps us to swim in the water. When our lungs fill up, we can swim higher in the water. When the air is placed in a restricted area, it is known as compressed air. It can be found in the tires of cars, bicycles, and planes used in flight mode.
- It reduces pollution: environmental pollution is a major problem since the current way of living leads to different kinds of pollutions. The ozone helps to minimize the level of environmental pollution.
- Wind energy (electricity): the wind can be used to generate electricity with the help of wind turbines installation. Such turbines rotate under the influence of the wind and generate electrical energy. This electrical energy is not polluting and can be generated anywhere on the Earth for domestic use.
These are not all the ways to use this natural resource. More interesting facts are waiting for you further!
Uses of air resources
As a natural resource, the air is very useful, just like water, and it has lots of applications. The most critical aspect of it is that it supports the vitality of all living beings on Earth, providing them with oxygen.
However, oxygen is not only useful for living things. Candles, iron, fire, collected fruits and vegetables tend to change under the influence of oxygen. For example, candles and fire need oxygen to continue to burn. Iron rusts when exposed to water and oxygen. Fruits and vegetables will change colour and eventually become mouldy due to the moisture and oxygen in the atmosphere.
It is also very important in cooking. Bread and cakes are filled with air holes. Due to these holes, they are light and fluffy. Another example is chocolate mousse which becomes airy and light. Drinks that supply it are called aerated - an example of such beverage is a soft drink.
Air is something that surrounds us every day, and its uses seem to be so trivial, and there are still people who do not pay much attention to one crucial thing: without it, our existence is doomed.
Uses of air pressure
The pressure helps in reducing friction in the tires: the cars are another thing where the importance of air is evident since car tires are filled with it in rubber tubes. With the development of technology, we have self-closing tubes, tubeless tires, etc.
However, these tires are not airless. This happens because it inflates the tire and this helps to reduce friction. The reduction of friction allows the car to move easily.
Uses of air to plants
In addition to everything else, plants can not survive without oxygen, carbon dioxide, and other elements. They need it for breathing and photosynthesis. This way, they convert food into energy. It is extremely vital for the growth of plants and their functionality.
Chemical uses of air
Carbon dioxide, oxygen, nitrogen, argon, and all the other components all have their own use and functions. The chemical composition of what we breathe with contains 78% nitrogen and about 21% of oxygen. There are also such components as carbon dioxide, which has some influences on human health, such as helping us sleep and relax.
Uses of air for kindergarten
There are a lot of pre-school activities connected with the discussion and use of our main breathing source. Particularly, there are some interesting ideas of uses of air for kids project.
- You can read the story "Air Is All Around You" by Franklyn M. Branley, and then help the kids think about how it influences our life. They can also draw what they learned from the story.
- The preschoolers can attempt to create windsocks with the help of construction paper, oil pastels, and a stapler.
- The kids can do some basic breathing exercises and feel their lungs filling with oxygen. Then, they can be physically active and see how much their breathing pattern changes.
- If the kids love music, they can play a variety of instruments which require wind to make unique sounds.
- The children can also blow bubbles and experiment with their size and shape.
As we can see, the air is one of the main things in our daily life. We will not be able to do anything without it, and we need it not only for breathing and life support. It helps us to live in a comfortable environment and a stable temperature.
