[Biology Class Notes] on Different Uses of Air Pdf

Air is a mixture of higher proportions of gasses such as oxygen, nitrogen and carbon dioxide, and much lower quantities of argon, water vapour, and other pollutants. Living people live and the pure gas breathes. The shape and composition are indefinite

It has no scent or colour. Air is a matter so it has mass and weight. Atmospheric pressure is created by the weight of air. The air constituents are 78 % nitrogen, 21 % oxygen, 0.9% argon, 0.04% carbon dioxide, and very small amounts of other gases and water vapour. Animals need to breathe the dissolved oxygen through aerobic respiration.

In breathing, we inhale oxygen that reaches the lungs and capillaries from the blood of the lungs absorb oxygen and breathe out carbon dioxide into the air.

Breathing is a consequence of the respiration process. A living thing absorbs oxygen from the air through respiration and lets off carbon dioxide. This process gives plants and animals the energy they need to eat, grow, and live life.

As humans and animals breathe there is emitted an odourless gas called carbon dioxide, or CO₂. In comparison to sunshine, plants use this gas to make food— and oxygen too. This is called photosynthesis. Nonetheless, as cars and power plants burn coal, oil, and gasoline, big amounts of CO₂ are produced. This is bad since CO₂ is the major contributor to global warming caused by humans.

The air in our environment is a protection that prevents the Planet from becoming too cold or too hot. Ozone, another form of air-borne gas, often defends us against too much sunshine. Air in the environment will shield us against meteoroids too. If meteoroids come into contact with our atmosphere, they brush against the air and are often burned in small pieces until they reach Earth.

Importance of Air

Air is necessary for every living thing on Earth to breathe. It provides the processes of oxidation which provide the required energy to the body. However, it has the largest application in various industry sectors.

Uses of Air

Air is a Substantial Supplier of Energy: To produce useful energy, both living plants and animals depend on oxygen. Body cells obtain oxygen from the blood and generate electricity in the form of ATP after eating food. This biochemical development of ATP is important if life on Earth is to survive. That is, then, one of the air applications.

It is a Conducting Medium for Sound: Only when there’s the air surrounding us we can hear the sound of the voice, vibration, etc. It does happen because the wind is a good conductor of air. We won’t be able to hear anything without a device and will not be able to produce the effects.

It is an Essential Part of the Water Cycle: The water cycle is a process of soil water, oceans, and seas evaporating by the heat of the sun and clouds formation. Such clouds move toward the surface of the land, and the wind and rain cool them off. This rainwater reaches the sea and the ocean once more.

It is Responsible for the Pollination of Crops: In pollen-grains, plants produce male gametes. Such pollen grains transfer from the male flower to the female flower and mix with female gametes, called pollination. With the aid of wind power, this can occur in flowers growing on the same plant or between distant plants. This preserves temperature equilibrium on the surface of the Earth when it is summer. 

When the sun heats the surface of the Earth intensely, the surface temperature of the earth rises rapidly but it grows slowly on the surface of the ocean or sea (this is because a solid substance melts more than liquid water).

Thus, the air heated at the surface of the Earth rises, and the cold one from the surface of the sea transfers to the surface of the ground which minimizes the temperature rise.

It Helps in Drying (Moisture Balance): Due to air, the soil gets saturated from the rain dries. It is sticky on a rainy floor. Therefore, fewer warm or cold quantities of air mask the humid areas. The new dry surface layer absorbs humidity from the wet surface, and the cycle continues until the surface is dry.

It Also Helps Us to Swim in the Water.

We will float further up in the water as our lungs fill up. It is classified as compressed air when the air is put in a restricted area. It can be used in tyres used in the flight mode of cars, bicycles, and aircraft.

It Reduces Pollution: Environmental pollution is a major problem because various types of pollution stem from the modern way of living.

Wind Energy (Electricity): 

The wind can be used to generate electricity by the installation of wind turbines. Under the power of the wind, these turbines rotate and produce electrical energy. This electrical energy is not polluting and can be created for domestic usage anywhere on Earth.

Uses of Air Resources 

Unlike water, the climate is very good as a natural resource, and it has different uses of ventilation in daily life. The most critical aspect of this is that it maintains the strength of all living beings on Earth and provides oxygen to them. Yet oxygen isn’t just useful for living things. 

Under the power of oxygen, candles, carbon, heat, harvested fruit and vegetables tend to change. Candles and flames, for example, require oxygen to keep on burning. When exposed to water and air, iron rusts out.

Owing to the moisture and oxygen in the environment fruits and vegetables can change colour and gradually get mouldy. Cooking is very necessary, too. Air holes make up the bread and the pies. They’re light and fluffy, because of these gaps.

Another form is a chocolate mousse that is light and airy. Beverages providing it are labelled aerated-a soft drink is an indicator of such a beverage.

Air as a Mechanical Source 

The generation of electrical power requires the presence of air. Not only is oxygen essential for combustion – the process that causes fires to form and so powers most fuel-burning generators, machinery, and vehicles – but air may also be utilised to generate electricity directly. Wind can be used to generate power as it passes through a huge turbine. Despite its critical, life-sustaining significance in our lives, the air is frequently overlooked. Many corporations and factories pay little attention to how pollution impacts air quality because it is invisible and surrounds the earth.

Air for Plants 

For the formation of important life energy, all living beings, including plants and animals, rely on air oxygen. Body cells absorb oxygen from the blood and produce energy in the form of ATP from food. The metabolic production of ATP is a prerequisite for life on Earth to continue. Male gametes are produced by plants in the form of pollen grains.

Pollen from male flowers travels to female flowers, where it combines with female gametes.

This is referred to as pollination. This can happen within the same plant’s blossoms or between flowers that are separated by air wind. As a result, air aids cross-pollination in plants. Going into a mature farm will now produce nasal stuffiness since pollen promotes allergy to the nasal passage when inhaled. This is beneficial in agriculture since cross-pollination increases production.

Air as a Medium of Communication 

Only in the presence of air can we hear speech, cries, noises, and other sounds.

This is due to the fact that air is a good sound conductor. We cannot or do not hear noises if there is no air. With the change of air and sound combination, even musical instruments use resonance and bass.

Air in Water Cycle:

The water cycle is a phenomenon in which water from the earth, oceans, and seas evaporates and creates clouds as a result of the Sun’s heat.

These clouds pass over land, where they are cooled by the air and fall as rain.

This rainwater eventually makes its way back to the seas and oceans.

As a result, air aids in the transfer or migration of clouds towards the land, as well as cooling them to allow rain to fall.

Air as a Source of Temperature:

The temperature of the earth’s surface rises rapidly but slowly on the ocean or sea surface during summers when there is plenty of sunshine (this is because a solid surface gets heated faster than liquid water).

As a result, air heated on the soil rises, while cool air from the sea surface travels onto the earth’s surface, limiting the temperature rise.

Air Aids in Transportation: 

Flights and helicopters have become common modes of transportation. Air is the primary route of transportation for even birds and insects. Air travel is faster than land and ocean travel. The cars travel faster because there is less friction.

Furthermore, the journey is in vector mode, that is, it moves from one point to another in a straight line (so shortest route). As a result, there are fewer roadblocks, making travel relatively quick.

Rains moisten the earth, which is then dried by heat and air. The air near the wet surface is extremely moist. As a result, the moist air layers are replaced by less moist or dry air layers. The wet surface absorbs moisture from the new dry layer on the surface, and the cycle repeats until the surface dries. As a result, air assists in drying by maintaining humidity. Even when we wash our clothing, they dry in the same way.

Causes for Bad Quality of Air 

Climatic change and pollution are the concerns of the hour. Pollution is a major worry, as today’s lifestyle produces a variety of pollutants. Air pollution and noise pollution can both be reduced with the use of air. Due to the blockage of filthy gases in the atmosphere, our major cities would have been deserted if we didn’t have air.

Towns and cities are excellent places to live since the air blows and carry pollutants to far places.

Remember that pollution, as we know it, is the outcome of human activity. Because these contaminants have no place in the natural cycle, their entry into the environment can have negative consequences for plants, animals, and the ecosystem as a whole.

Pollution, like human health, may have a significant impact on the ecosystem, ranging from minor downsides to major imbalances. Pollution’s negative consequences on the environment include, but are not limited to:

1. Climate change has resulted in the proliferation of exotic species.

2. Toxic compound concentrations in the ground, water sources, or atmosphere

3. Carbon dioxide emissions have increased, lowering the pH of the world’s oceans.

4. Smog production is a process in which pollutants are released into the atmosphere.

5. Rainfall that is acidic
   

Clean Air has Several Blessings

While all types of pollution are very dangerous, air contaminants account for roughly sixty-six % of all deaths attributed to mass contamination. except for the very fact that contaminants move quickly once they are unit mobile, it’s simple to become exposed to pollution.

Simply respiration contaminated air will cause serious health issues, thus reducing mobile pollution is essential for humans normally. There are unit various blessings to respiration clean air, including:

1. Cleaner lungs

2. Reduced bronchial asthma and allergic reaction symptoms

3. Improved skin look

4. It aids digestion.

5. Psychological and emotional stabilizer

6. Improved mood and sleep patterns

7. Reduce your risk of respiratory organ, heart, and blood vessel sickness.
