what are the properties of air
Air is one of the most fundamental elements of life. It’s essential for breathing, and is used in manufacturing, transportation, and energy production. Knowing what the properties of air are can help you in a variety of situations.
The Properties of Air
Air is one of the gases that make up Earth’s atmosphere. It is composed of nitrogen, oxygen, and argon. The temperature of air ranges from -40 degrees Fahrenheit to over 300 degrees Fahrenheit.
The atmosphere is the layer of the Earth’s atmosphere that contains most of the planet’s air. It extends from the surface up to an altitude of about 30 kilometers. The Earth’s atmosphere is made up of gases, including nitrogen, oxygen, argon, and carbon dioxide.
The ozone layer is a protective layer that shields Earth from the sun’s harmful ultraviolet radiation. The ozone layer is made up of three parts:
The first part, called the stratosphere, is about 10 kilometers (six miles) above Earth’s surface. It’s made up of gases such as chlorine and nitrogen that are broken down by the sun’s UV rays.
The second part, called the mesosphere, begins at about 50 kilometers (31 miles) and extends to about 800 kilometers (497 miles). It’s made up of substances that are not broken down by the sun’s UV rays.
The third part, called the thermosphere, begins at about 1,000 kilometers (621 miles) and extends to about 25,000 kilometers (15,000 miles). It contains molecules that are broken down by UV rays.
Air is a mixture of gases, including nitrogen, oxygen, and argon. The gases are held together by the forces of thermal equilibrium.
The pressure and temperature of an air parcel are inversely related. That is, the higher the pressure, the lower the temperature. The temperature in degrees Fahrenheit (F) can be found by using the following equation: 100 + (5 x temperature in degrees Celsius)
The atmospheric pressure is about 14.7 pounds per square inch (psi).
The Properties of Air
The properties of air are temperature, pressure, and volume.
The Percentage of Air
The percentage of air is 78% nitrogen and 22% oxygen. This makes air a mixture of gases.
The Temperature of Air
The temperature of air is about 1000 degrees Fahrenheit.
The Pressure of Air
The pressure of air is measured in units of pounds per square inch (PSI). The higher the pressure, the greater the force against which something else is pressed. The atmospheric pressure at sea level is 14.7 PSI. The pressure inside a car at cruising speed is around 30-35 PSI.
When you breathe in, air fills your lungs and then leaves through your mouth and nose. This process creates a vacuum, and as the pressure inside the lungs gets higher than the atmospheric pressure outside, atmospheric pressure starts to fill in on either side of your lungs. Your breathing muscles push down on blood vessels in your lungs, pushing blood up to your brain and other vital organs. This increase in blood pressure makes it difficult for carbon dioxide to leave your bloodstream and enter cells, causing cellular acidosis (a condition characterized by an excessive amount of acid in the bloodstream).
The properties of air are constantly changing, and scientists are still trying to understand all of the ways that this invisible gas affects our lives. Some of the most notable properties of air include its ability to move objects and molecules (through convection), its ability to create sound waves, and its role in climate change. As we continue to learn more about how air affects our world, it will be important to keep these properties in mind when designing buildings and products that rely on air transportation or production processes.
