It is noted that a suspension, which is another kind of liquid mixture, greatly differs from a solution. A suspension may be demonstrated by placing some sand in a glass of water and then stirring the mixture violently for a moment. If this is done, the two substances mix but no solution is effected. The particles of sand, being larger than any of particles of the true solution, mix for a while, but since they move about less freely, they finally settle on the bottom when agitation of the mixture ceases.

Electromagnetism and gravity are two basic forces of nature. They are very similar and scientists are trying to unify them. Electromagnetism works in small objects – it attracts the electrons from the atomic nucleus and maintains them in place. Gravity works with big objects – the pull of gravity from the nucleus of the Earth maintains our atmosphere in place. Both, the electrons and the Earth, spin and generate an electric and magnetic field around them. These fields make up our planet’s electromagnetic shield.

Benjamin Franklin is acknowledged to be the founder of the theory of atmospheric electricity. He was the first to prove that the lighting was an electrical phenomenon. Franklin developed a new theory of electricity that he called positive and negative. He finally invented a means of protection against the disastrous effects of lighting – the lighting rod. Franklin is known and respected all over the world not only as a scientist but also as a citizen who did as much as he could for the good of his country. Coming out in defence of the Afro-Americans, Franklin declared slavery to be not only an evil from the moral point of view, but also an obstacle to the social interests of America. He is thought to be one of the broadest as well as one of the most creative minds of his time.

Scientists have recently come to believe that 1_______ in solutions and liquid mixtures behave very much as they behave in gases, 2_______, and solids. For instance, when two substances, such as sugar and water, are combined by dissolving, the particles of the solvent divide the particles of the solute, and the two kinds of particles then 3_______ freely. This is a 4_______ solution.
