F.,
and 69.12 in the same liquids at 160 deg. F.; and the proportion in which
it was the most chemico-electro-positive at 60 F. was 84.44 per cent,
and at 160 deg. F. 80.77 per cent. The proportion of cases therefore in
which the most chemico-electro-negative metal was the most corroded
one increased from 15.56 to 19.23 per cent, by a rise of temperature
of 100 deg. F. Comparison of these proportions shows that corrosion
usually influenced in a greater degree chemico-electric rather than
thermo-electric actions of metals in liquids. Not only was the
relative number of cases in which the volta-negative metal was the
most corroded increased by rise of temperature, but also the average
relative loss by corrosion of the negative to that of the positive one
was increased from 3.11 to 6.32.
The explanation most consistent with all the various results and
conclusions is a kinetic one: That metals and electrolytes are
throughout their masses in a state of molecular vibration. That the
molecules of those substances, being frictionless bodies in a
frictionless medium, and their motion not being dissipated by
conduction or radiation, continue incessantly in motion until some
cause arises to prevent them.
