Card preview (2)
State the distinguishing properties of solids, liquids and gases.
Solids: Particles tightly packed in a regular arrangement. Very strong intermolecular force. Fixed volume and shape. Not easily compressible. Liquids: Particles close together in a random arrangement. Moderately strong intermolecular force. Fixed volume but is fluid. Almost can’t be compressed. Gases: Particles very far apart in a random arrangement. No intermolecular force. Expands to fill container. Highly highly compressible.
Describe qualitatively the molecular structure of solids, liquids and gases.
Solids: Tightly packed, regular arrangement. Liquids: Less tightly packed, random arrangement Gases: Far apart, random arrangement
