This indispensable gas that promotes the life of living beings has its particular properties. And here in this article, you'll know what the Properties of air.
The air in the earth's atmosphere is a mixture of many gases as well as water vapor and suspended particles such as dust, chemicals, soot and others.
Air is made of:

Get to know the properties of air: Mass and matter, pressure, density, strength, compressibility, expandability and elasticity.
Air is made of matter, made up of various gases made of atoms. Therefore, air has a mass that will take up space. When blowing a balloon, it fills with air and takes up more space.
Air produces a pressure on the surface of the earth, this is called atmospheric pressure. The closer you are to the earth's surface, the greater the pressure, as the air tends to weigh more.
And as the altitude increases, the pressure decreases because with less air above, it becomes lighter.

Gravity is responsible for the weight of the air, gravity and the force that attracts everything that exists to the center of our planet. And for this reason, the concentration of gases is higher when close to sea level.
The air we breathe has more density than mountain air because at higher altitudes the air density decreases and becomes thin air.
The air tends to counteract any movement, this is called resistance. The greater the displacement, that is, the speed, the greater will be the air resistance.
Cars, boats or planes or any other type of vehicle is designed to reduce resistance during operation to save fuel.
The air can be compressed and expanded and then returned to the state it was in. When air reduces its volume, it is compressed, a process called compressibility.
If the compression stops, the air will go back to occupy the space it was in before, ie the elasticity. And when air expands, it increases its volume, which would be expandability.
