In explaining the watery solution of sugar, it has been stated that the 1_______ of such solutions divides the sugar into particles, called 2_______, so small that they cannot be seen with the naked eye. These molecules are distinguished by the great speed at which they 3________. Molecules, which are found in all substances, travel fastest in gases, less rapidly in 4_______, and very slowly in solids.

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.

Electric power is generated at power plants and it must be transmitted to other parts of the country. How is 1_______ transmitted to those parts? Thick 2_______ carry electric power over long distances. The wires are not always made of copper, often they are made of other 3_______.
A number of wires put together form one thick 4_______. A cable consists of a number of wires put together and a pair consists of two insulated conductors forming a metallic circuit.

Dynamo is a common 1_______ for converting mechanical energy into electric energy. This process 2_______ on the fact that if an electrical conductor moves across a magnetic field, an electric current flows in the conductor.
Usually a 3_______ includes an electromagnet, called the field magnet, between the poles of which a suitable conductor, usually in the form a coil, called the armature, is rotated. The mechanical energy of the rotation, in the form of a current in the armature, is thus converted into 4_______ energy.
