Nowadays, hemorrhoids or piles are a very common problem among the people. The most common reason behind this is our changed lifestyle and unbalanced diet. Pregnant women also suffer from this problem commonly. Actually, piles is a bunch of veins which surrounds the anus but when these start to extend out of their usual place because of over straining due to any reason, this turns into a disease which we call as piles or hemorrhoids. However, it is not so difficult to deal with piles. We can get rid of piles with help of some natural ingredients.
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon),elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture would contain a variety of pure gases much like the air. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colorless gas invisible to the human observer. The interaction of gas particles in the presence of electric and gravitational fields are considered negligible as indicated by the constant velocity vectors in the image. One type of commonly known gas is steam.
