A solid body has a definite form, and tends to keep it; a liquid body must be kept in a vessel and adapts itself to the shape of that vessel, but so as to keep its upper surface horizontal, it tends, moreover, to flow from a higher to lower level. A gas, or a gaseous body, cannot be kept in an open vessel, but must be kept in a vessel closed in all sides; it always fills the vessel completely.

Tin is a silvery metal which is not corroded by air. The chief use is for making tin plate, i.e. sheetiron coated with tin. Tin plate is suitable for cans in which acid fruit and other food-stuffs are packed because tin is not attacked by weak acids. For good containers, iron is coated with tin instead of zinc because tin is not subject to attack by acids in food.

Atomic energy must serve peaceful purposes only. This is what Academician Igor Kurchatov (1903-1960) worked for until his death.
His team of scientists worked on application of atomic energy in such fields as chemistry, geology, biology and medicine. Academician Kurchatov headed the Atomic Energy Institute of the USSR Academy of Sciences (which is now bears his name) where a great deal of progress has been made in the complicated field of controlling thermo-nuclear reactions.
In 1940 Flerov and Petrzhak, two Russian Scientists, experimentally detected spontaneous nuclear fission of uranium and determined its average life-time.

Yellow and brown diamonds are good only for industrial purposes and cost much cheaper than the white and blue ones. But with the coming of nuclear age, the colour of the diamonds can be changed by radiation from a nuclear reactor.
A nuclear reactor emits neutrons which give diamonds a greenish colour.
Beta rays produced by a cyclotron colour the diamonds blue. In both cases the colour changes as a result of the impact of the atomic particles on the diamonds’ structure. The radiated diamonds do not become radio-active and can be worn safely.
