Question

the particles in water have less mobility than the particles in oxygen. which statement best explains this observation? water is always colder than oxygen. water has a lower density than oxygen. water particles have a greater kinetic energy. water particles have strong intermolecular forces.

Explanation:

Intermolecular forces affect particle mobility. Stronger intermolecular forces in water restrict particle movement compared to oxygen where particles have weaker attractions and more freedom to move. Water is not always colder than oxygen, has a higher density than oxygen in common states, and particles with greater kinetic energy would have more mobility.

Answer:

Water particles have strong intermolecular forces.
