Matter & Energy


Matter is composed of atoms or groups of atoms called molecules. The arrangement of particles in a material depends on the physical state of the substance. In a solid, particles form a compact structure that resists flow. Particles in a liquid have more energy than those in a solid. They can flow past one another, but they remain close. Particles in a gas have the most energy. They move rapidly and are separated from one another by relatively large distances.

Carbon Disulfide

.
Carbon Disulfide, colorless, extremely volatile and flammable compound with a disagreeable, fetid odor. It is used as a solvent for oils, fats, and waxes; as a reagent in the manufacture of regenerated cellulose; as the starting material in the manufacture of carbon tetrachloride; in rayon and cellophane production; and in the vulcanization of rubber. Carbon disulfide is made by heating carbon and sulfur together or by the reaction between methane and sulfur vapor. It freezes at -111.53° C (-168.75° F) and boils at 46.25° C (115.25° F).
