O atmospheric air it is a mixture of gases that surround the Earth.
It has many properties such as expandability, compressibility, elasticity and atmospheric pressure that is exerted on the Earth.
We prepare a list of exercises about air properties so you can test your knowledge of atmospheric air.
You can consult the feedback and save this list in PDF at the end of the post.
