OXYGEN.
Symbol O. Atomic Weight 15.9.
Priestly, in England, discovered oxygen on the first of August 1774, when he heated oxide of mercury by means of the sun's rays concentrated by a burning glass. It was afterwards discovered independently by Scheele, in Sweden, in 1775.
Properties of Oxygen. Oxygen is at an ordinary temperature a colourless, odourless and tasteless gas, heavier than air and slightly soluble in water. 100 volumes of water at 0° can dissolve 4 volumes of oxygen under the normal pressure of 760 mm. It is converted into a liquid at a low temperature and a high pressure. It boils at — 181o C.
Occurrence. Of all the elements which occur on our planet oxygen either free or combined is the most widely diffused and is found in the largest quantity. Oxygen occurs in the free state in the atmosphere, of which it forms one fifth by volume. In combination with hydrogen it forms 8/9 of the total weight of water on the earth's surface. It occurs very plentifully in a state of combination in all rocks and is an essential constituent in all animal and vegetable structures.

SHOPS AND SHOPING.
The face of the towns and villages in Uzbekistan is changing. We see new houses, schools, cinemas and shops in every town. Shops are very important in our life. There are different kinds of shops. Some of them sell bread. Others have tea, sugar, coffee, butter, cheese, sausages, meat or fruit. When we want to buy something, we take our shopping bag and go to a shop. There we talk with shopkeepers who sell things.
Many people do their shopping at the market. There, farmers sell vegetables and fruit that they grow themselves. They sell meat, milk and other things too.
Big shops with many departments are called stores. In stores we can buy almost anything we like. In the windows we see all the things that they sell: food, suits, dresses, coats, boots, shoes, radios, TV sets and many other things.
When we want to buy clothes we go to a department store. This is a big store with many departments where clothes, textiles, linens and jewelers are sold.
