NOT A HWK QUESTION Molecular Theory PLEASE.

    NOT A HWK QUESTION!! Molecular Theory PLEASE.

    Hi, Does anyone know the veracity of the quotation of experiments by Francis Bacon, in some books published around the turn of 20C., stating that he filled metal spheres with water and, upon applying sufficient pressure, saw water droplets on the outside of the spheres indicating that the water molecules came through between the metal particles - so there are spaces between the metal atoms. It's interesting to read book like 'Heat considered as a mode of motion' as recommended by Clerk Maxwell or Millikan. Thanks for your time.

    That's not what Bacon wrote. Quoting the Novum Organum:
    He didn't see the water diffuse through the metal, he saw the water spray out of a fissure. Water doesn't diffuse through metal. (Nor did he know anything about atoms, which came centuries later)

    What he did do, was an excellent demonstration of the compressibility of water, which is what he intended to study.

    If water could diffuse through metals, it would be a sad, sad story for submarines.

    I guess we could even use glass then, for the viewing pleasure :wink:
