Why do you think that liquids have less kinetic energy compared to gasses?
Equipartition theorem (Equipartition theoremhttps://en.wikipedia.org/wiki/Equipartition_theorem) states that average kinetic energy is the same per degree of freedom and is $kT/2$1/2 * k * T. The motion of a molecule of water inside a liquid is jittery, but still the molecule has 6 degrees of freedom so the kinetic energy should be the same.
This may look counter-intuitive. We heat water, water evaporates, energy consumed $\rightarrow$=> molecules in gas should move faster. Isn't it? Actually the energy goes to breaking the attractive forces between molecules in liquid.
