Document Summary
Gas molecules are packed close to each other in xed locations molecules are packed close, bur are free to move around and by each other atoms or molecules are widely separated and free to move relative to one another. Amorphous atoms or molecules are arranged in a well-ordered, three-dimensional array with long- range repeating order atoms or molecules that do not have long- range order; e. g. glass and plastic. Gases are compressible (able to occupy a smaller volume when subjected to increased pressure) because they are widely separated. Motion oscillation or vibration about a xed point free to move relative to one another free to move relative to one another. Physical and chemical properties of matter properties- characteristics used to distinguish one substance from another physical vs. chemical properties a substance displays without changing its composition properties a substance can display.
