  1. 1. change also known as a chemical reaction, is a process in which one or more substances are altered into one or more new and different substances. In other words, a chemical change is a chemical reaction involving the rearrangement of atoms.
  2. 4. the phenomenon in which light is scattered by particles of matter in its path. It enables a beam of light to become visible by illuminating dust particles, etc
  3. 6. is a characteristic of matter that can be observed and measured without changing the chemical identity of the sample. a physical property might involve a physical change but not a chemical change.
  4. 8. dispersed in a continuous gaseous, liquid, or solid medium whose properties depend on the large specific surface area.
  5. 11. the principle that in any closed system subjected to no external forces, the mass is constant irrespective of its changes in form; the principle that matter cannot be created or destroyed.
  6. 12. one of a class of substances that cannot be separated into simpler substances by chemical means.
  7. 13. a species of matter of definite chemical composition
  8. 14. change involve states of matter and energy. No new substance is created during a physical change, although the matter takes a different form. The size, shape, and color of matter may change. Physical changes occur when substances are mixed but don't chemically react.
  9. 15. mixture is a mixture in which the composition is uniform throughout the mixture.

  1. 2. a substance made up of a system of particles with linear dimensions dispersed in a continuous gaseous, liquid, or solid medium whose properties depend on the large specific surface area.
  2. 3. the process by which a gas, liquid, or solid is dispersed homogeneously in a gas, liquid, or solid without chemical change.
  3. 5. any of the properties of matter that can be observed and measured only by performing a chemical change or chemical reaction. Chemical properties cannot be determined by touching or viewing a sample; the structure of the sample must be altered for the chemical properties to become apparent.
  4. 7. the purification or concentration of a substance, the obtaining of the essence or volatile properties contained in it, or the separation of one substance from another, by such a process.
  5. 9. the state in which the particles of a substance are mixed with a fluid but are undissolved.
  6. 10. mixture composed of different substances or the same substance in different phases, as solid ice and liquid water.
