It is the energy associated with molecular motion, including translation, vibration, and rotation.
Associated with this faster molecular motion is an elevation of pressure inside the bottle.
Depending on the particular effect of the additive, you can restrict molecular motion, or increase it.
Its natural temperature is almost absolute zero, the point where all molecular motion stops.
It was slow work because they had to use the heat ray pistols to supply the necessary energy for the molecular motion.
The extra energy can be converted into molecular motion and lost as heat.
So it must be some way of turning molecular motion of heat into electric power.
His initial interest was in molecular motion in organic systems.
Steam rose from it; she had heated the water without fire, by speeding up molecular motion.
Under such conditions of increased molecular motion, their grip on each other weakens.
