Question

At room temperature, 20°C, water (H2O) is a liquid and oxygen (O2) is a gas. Based on kinetic molecular theory, which answer best describes the states of the two fluids?

Answer 1

The particles in the liquid have greater kinetic energy than the particles in the gas.
The particles in both substances are able to fill any container because both have indefinite shape and indefinite volume.
The particles in both substances are able to flow because of weak intermolecular forces.
Water molecules have a lower boiling temperature than oxygen molecules, so at room temperature they exist as a liquid rather than a gas.
