For, the loss of heat being simply the abstraction of molecular motion by the aether, where this medium is absent no cooling could occur.
While Faraday was so successfully developing the principles of electrical action, Graham with equal success was investigating the laws of molecular motion.
This of Professor Haeckel tries to go deeper, and to explain organic phenomena in terms of molecular motion.
Now, we believe that the particular kind of molecular motion which we call neurosis, or brain-action, has been evolved.
Or we apply heat, a mode of molecular motion, to a bar of metal which expands, to a mixture of hydrogen and oxygen which unite chemically.
At once chemical action, a form of molecular motion, is set up.
The molar motion of hands, a piece of silk, and a glass rod results in electricity, a mode of molecular motion.
The coal which supplies the force exerted in combustion is not shown to have been exerting that force in the form of molecular motion in the pit; it was not even exerting pressure.
Now there is a real basis of fact for this supposition: we have positive evidence of the existence of molecular motion in these manifestations of force.
At this time we are to consider the evidences of molecular motionin gases.
This experiment demonstrates not only the fact of molecular motion in gases but also that molecules of hydrogen move much faster than those of air.
Let us now consider some of the evidence of molecular motion in liquids.
Among the higher birds and mammals the amount of conscious life is very considerable, and here too it must be argued that consciousness is not a product of molecular motion in the nervous system but its concomitant.
All are specific modes of molecular motion, transformable one into another at any moment as naturally as a cloud condenses into raindrops.
If consciousness is a product of molecular motion, it is a natural inference that it must lapse when the motion ceases.
Corrosion therefore is an effect of molecular motion, and is one of the modes by which that motion is converted into and produces electric current.
But, then, the question remains, What is the intellectual perception or mental cognition of the idea suggested by one of these supposed transmissions of a wave of molecular motion?
This idea lasts while the waves of molecular motion last, ceasing when they cease; but that which remains is the set of plexuses.
It is true that solid metals, wood and stones are in a constant state of molecular motion.
He says further: "Heat is believed to be a certain mode of molecular motion, and electricity to be another mode; but the nature of the motion of each has never been discovered.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "molecular motion" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
