Introduction to Air Pollution
Air pollution is the introduction of chemicals, particulate matter, or biological materials into the Earth’s atmosphere that can cause harm to humans, animals, or plants. Air pollution can take the form of gaseous pollutants, solid pollutants, or liquid pollutants.
The primary pollutants that cause air pollution are sulfur dioxide, nitrogen oxide, ozone, carbon monoxide, and lead. These pollutants are released from automobiles, power plants, and other industrial sources.
Air pollution can cause a variety of health problems, including respiratory problems, heart problems, and neurological problems. Air pollution can also cause environmental problems, such as acid rain and global warming.
Properties of Air
There are many properties of air that make it a vital component to life on Earth. Air is a mixture of gases that make up the Earth’s atmosphere. The main component of air is nitrogen, which makes up about 78% of the atmosphere. Oxygen is the second most common gas in air, making up about 21%. Argon is the third most common gas in air, making up about 0.93%. Other gases make up about 0.01% of the atmosphere.
Air has many properties that are necessary for life. Air is a good insulator, meaning it helps to keep heat in or out. This is why air is used in insulation materials. Air also has a low density, meaning it takes up a lot of space. This is why air is used in inflatable objects, such as air mattresses and balloons.
Air is also a good conductor of sound. This is why air is used in loudspeakers. Air also has a low viscosity, meaning it is not very thick. This is why air is used in air brakes and air tools.
Air is a necessary component of life on Earth. It is used to insulate objects, conduct sound, and has a low density. Air is also a good conductor of heat.
What Does Air around Us Contain?
Air is a mixture of gases surrounding the air. The other 1% is made up of argon, carbon dioxide, helium, hydrogen, krypton, methane, neon, and xenon. These gases are essential to life and are necessary for humans, animals, and plants to breathe. Without air, we would not be able to survive.
