This overview details the three primary states of matter: solids, liquids, and gases. Solids have both a definite shape and volume, with molecules closely packed and vibrating slowly. Liquids maintain a definite volume but have no fixed shape; their molecules are slightly separated and move at medium speeds. Gases, on the other hand, have neither a definite shape nor volume, characterized by rapidly moving and widely spaced molecules. Understanding these properties is essential in the study of physics and chemistry.
E N D
SOLID • Has a definite shape and definite volume. • Molecules are very close together and slowly vibrating against one another
LIQUID • Has a definite volume but indefinite shape (NO definite shape). • Molecules slightly separated and moving at a medium speed.
GAS • No definite shape, no definite volume (indefinite shape, indefinite volume) • Molecules moving rapidly( quickly) around and very spread out
