Our atmosphere, to which we are uniquely adapted, is about 78% nitrogen, 21% oxygen, and 1% everything else. It has changed very gradually over the millions of years, but that's where we are right now. Let's not mess with it.
The Earth will not run out of air. The atmosphere contains a constant supply of oxygen and other gases that support life on the planet.
No, we will not run out of air on Earth. The Earth's atmosphere contains a constant supply of oxygen and other gases that support life.
The air we breathe primarily consists of nitrogen (about 78%) and oxygen (about 21%). Other gases present in smaller amounts include argon, carbon dioxide, and trace gases such as neon, helium, and methane.
A mixture of many gases is commonly known as air. Air is composed of different gases such as nitrogen, oxygen, carbon dioxide, and others in varying proportions.
The atmosphere is the part of the Earth system that contains the air we breathe. It is composed of gases such as oxygen, nitrogen, and carbon dioxide and plays a crucial role in supporting life on Earth.
The Earth will not run out of air. The atmosphere contains a constant supply of oxygen and other gases that support life on the planet.
No, we will not run out of air on Earth. The Earth's atmosphere contains a constant supply of oxygen and other gases that support life.
The air sacs (alveoli) have a very large total surface area and a very good blood supply. There is an exchange of gases between the air sacs and their surrounding capillary blood vessels. Oxygen diffuses from the air sac into the blood. Carbon dioxide diffuses from the blood into the air sac.
Well I think its true
What gases cause air pollution
Yes, we breathe in a mixture of gases that includes nitrogen, which makes up about 78 of the air we inhale.
Yes. The gases ARE the air.
There are three ways. Some mixtures are gases themselves, and air is the most common one. Some mixtures are partly gases and partly liquids. Also, gases can dissolve into liquids, like oxygen in water.
Gases displace oxygen, and heavy gasses will sit under oxygen containing air, hence if you are in a confined space it is necessary to know about the potential lack of air supply to breathe, aswell as the potential of combustion and the like.
Noble gases are lighter than air. Hence balloons filled with noble gases will float in air.
No, humans do not breathe in nitrogen as a part of the air they inhale. The air we breathe is mostly made up of oxygen, with a small amount of other gases like nitrogen and carbon dioxide.
Yes. Neon is a part of noble gases (or inert gases)
