1. Solids like tablets and cellphones have definite s__________ and volume because the particles are packed c_________together in fixed positions. Thus, particles in solids are incompressible. 2. Liquids like water solutions and juices have definite v____________ but no definite shape. particles are closer to one another but they can move a__________ each other that made them to flow. 3. Gases like air and oxygen have indefinite shape and volume. P___________are very far from each other; this explains why a gas spreads and fill all the available s___________in the container.
