Question 1 • IA-Chemistry A Survey of Chemistry A

The particles in water have less mobility than the particles in oxygen. Which statement best explains this observation?

Answer
A
Water is always colder than oxygen.
B
Water has a lower density than oxygen.
C
Water particles have a greater kinetic energy.
D
Water particles have strong intermolecular forces.

Explanation

Water particles attract one another strongly because water molecules form hydrogen bonds. These strong intermolecular forces restrict how freely the particles can move, so they have less mobility than oxygen particles. Greater kinetic energy would generally increase particle motion, not explain reduced mobility.
