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

Question

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