Explanation:
Air is a mixture of gases like oxygen, nitrogen and carbon dioxide in higher proportions and much smaller levels of argon, water vapor, and other gases. Living things live and breathe in the clear gas. It has an indefinite shape and volume. It has no color or smell. Air is a matter so it has mass and weight. The weight of air creates atmospheric pressure. The Components of air are 78% nitrogen, 21% oxygen, 0.9% argon, 0.04% carbon dioxide, and very small amounts of other gases and water vapor. In aerobic respiration, animals need to breathe the oxygen in the air. In breathing, we inhale oxygen which reaches the lungs and from lungs blood capillaries absorb oxygen and carbon dioxide is breathed out into the air. Plants need carbon dioxide for photosynthesis
Important Uses of Air
Air is a natural resource and is available abundantly. It is an essential element of nature that support life on earth. Air is equally important for living organisms for their survival just like water. Air is very useful and has many applications. Uses of air are as follows:
Sustain life and growth
Combustion
Maintaining Temperature
Supplier of Energy
Photosynthesis
Sustain Life and Growth
Oxygen present in the air is one of the main life-sustaining gas. All living things breathe in and breathe out the air in the form of oxygen and carbon dioxide. Nitrogen and Carbon dioxide are vital for plants and their growth.
Combustion
Another use of air is that it supports burning or combustion. The oxygen present in air help in the burning of the fuels leads to carry out activities like cooking food, running industries, and vehicles as well as generating heat and electricity.
Temperature Control
Air helps in maintaining the temperature on the earth’s surface by circulating hot and cold air. Air acts as a conductor of heat. The phenomena of the water cycle are also dependent on air.
Supplier of Energy
Air which consists of energy is one of the main suppliers of energy. Living things are made up of cells and these cells extract oxygen within the blood to produce energy in the form of ATP. The generation of ATP which is biochemical in nature is essential to maintain life on the Earth.
Photosynthesis
Carbon dioxide which is also a component of air is used by plants during the process of photosynthesis and oxygen, water vapor is released by plants as a by-product.
Answer:
Example Gases
Oxygen (O2): medical use, welding. Nitrogen (N2): fire suppression, provides an inert atmosphere. Helium (He): balloons, medical equipment. Argon (Ar): welding, provides an inert atmosphere for materials.We breathe air. So it's useful to us because we would suffocate without it. ... And all the air on Earth together, called the atmosphere, protects us from harmful space radiation and from most meteors, which burn up in the atmosphere. Also the atmosphere traps heat from the Sun which, up to a point, is very useful.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.Having said that, just like water, the air is very useful and it has a lot of applications.
