PHENOMENA OF
CAPILLARITY
After that I
separately
calculated the values for
Cl,
Br,
and J;
these
determinations
are
of
course
less reliable.
I
found:
cl
60,
Br
=
152,
CJ
=
198
I present
the data in the
same
way
as

It
seems
to
me
that the
larger
deviations
from
our
theory
occur
for
those
compounds
that
have
relatively
large
molecular
masses
and
small
molecular
volumes.
Based
on
our
assumptions,
we
found
that the
expression
for
the potential
energy per
unit
volume
is
(£ca)2f-
P
=
P
-
K
,
OD
VZ
where
K
denotes
a
definite
quantity, which
we,
however,
are
not
able
to
calculate because it is
only
defined
completely
by
the choice
of the
c^'s.
