Solids, Liquids, and Gases Practice Test

In both phases, the molecules are in close contact, but only in the gas phase do they have translational motion.

In the solid phase, molecules are widely separated; in the gas phase, they are in close contact but move freely.

In the solid phase, intramolecular bonds are broken; in the gas phase, individual C and O atoms exist.

In the solid phase, molecules are held in a fixed lattice; in the gas phase, they are widely separated and move randomly.
