The
author bases himself
on a
relation
between
the heat of fusion
l,
the (absolute)
melting temperature
T1,
and
the
specific
heat
at constant
temperature
cp,
which he had
derived earlier
by
elementary
considerations
based
on
molecular
theory, and which
is
expressed
approximately
by
the formula
l
=
0.382cpT1.
This formula
proves
to be
valid with
rough
approximation
for
elements
as
well
as
for
compounds.
A
few
substances for
which
the
formula
does
not
hold
even
approximately
(sulfur,
phosphorus)
are
also presented.
Incidentally, it should
be
noted that
up
to
the numerical value of the
constant,
the relation
presented,
extended
to
the
solid
aggregation
state, is
a
consequence
of the
law
of
corresponding
states. Finally,
a
molecular-
theoretical
consideration, which
shall
not
be
presented
here,
leads
the
author
to
the view
that
one
obtains the
best
agreement
of
the
theory
with
experience
when
one
ascribes linear
harmonic oscillations
to
the
atoms
of
simple
solids.
