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 hold particles in liquids (like water) closer together and restrict their movement, while gases (like oxygen) have weak intermolecular forces, allowing particles to move freely. The other options are incorrect: water is not always colder than oxygen, water has a higher density than oxygen gas, and higher kinetic energy would increase particle mobility, which contradicts the observation.

Answer:

Water particles have strong intermolecular forces.
