The amount of helium in the air
Air is an essential part of life, it is a mixture of many gases. Among them, nitrogen and oxygen are the main components, which occupy the majority of the air. However, the air also contains other gases such as carbon dioxide, hydrogen, helium, and so on. Among them, helium is a very special gas because it is one of the rarest gases on Earth.
The amount of helium is very small, occupying only 0 percent of the air0005% or so. This may sound like a small number, but in reality, helium has very important applications in many ways. For example, in the medical field, helium is used to make MRI machines that can help doctors diagnose conditions more accurately. In addition, helium is also used to create helium balloons, which can float in the air, making them ideal for celebrating various festivals and events.
Although helium is very small, it is very widely distributed on Earth. Helium is mainly found in the Earth's atmosphere, but also in natural gas and oil underground. Due to the very low amount of helium in the air, it is rare, but it has very important applications in many ways. Bring more welfare and convenience to human beings. Coupled with the fact that it is very difficult to mine and extract, the ** of helium is also very expensive.
