...of their size we must betake ourselves to a scheme of threefold magnification. Lord Kelvin has shown that if a drop of water were magnified to the size of the earth the molecules of water would be of a size intermediate between that of a cricket ball and of a marble....

...considerable degree of certainty. Lord Kelvin's famous comparison in regard to the size of molecules is this : If a drop of water were magnified to the size of the earth, the molecules in it would be smaller than cricket balls but larger than fine shot. 128. Porosity. — If...

...more than a hundred layers of molecules. Lord Kelvin illustrates the size of a molecule by stating that if a drop of water were magnified to the size of the earth the molecules would be about the size of an orange or a cricket ball. Although the molecule is the unit...

...molecules in a row would be required to make a length of one millimeter. Lord Kelvin has estimated that if a drop of water were magnified to the size of the earth, " the structure of the mass would then be coarser than that of a heap of fine shot, but probably not so coarse...

...understood. Matter is made up of particles called molecules, so small, that Sir William Thomson estimated that if a drop of water were magnified to the size of the earth, the molecules of water would each be less than the size of an ordinary baseball and larger than small shot....

...volume; ie, they have length, breadth, and depth, or occupy space in three directions. Kelvin estimates that if a drop of water were magnified to the size of the earth, the molecules would be larger than small shot, but smaller than cricket balls. The atoms would, therefore,...

...figures called crystals. More or less approximate attempts to calculate the size of the molecules show that, if a drop of water were magnified to the size of the earth, the size of the molecules of water would be between that of small shot and of cricket balls. Molecules...

...particles, called " atoms." It will give you some idea of the unthinkable smallness of these atoms to know that if a drop of water were magnified to the size of the globe, the molecules of water composing it would be the size of oranges. This is all too difficult...
