Summary: kalzium reports melting and boiling point with
specification of the chemical structure
Product: kalzium
Version: unspecified
Platform: unspecified
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
AssignedTo: kalzium at kde.org
ReportedBy: egonw at users.sourceforge.net
Version: 2.3.80 (using 4.4.2 (KDE 4.4.2), Kubuntu packages)
Compiler: cc
OS: Linux (x86_64) release 2.6.32-21-generic
Chemical elements are concepts, not physical entities. Atoms are, but even a
single atom does not have all physical properties. Melting point is a property
of a solid of some chemical structure; boiling points is a physical property of
a liquid of some chemical structure.
Now, Kalzium reports melting points and boiling points *without* reporting the
substance for which it is reported. For example, it reports a melting point for
hydrogen, and assumingly this refers the the molecule H2 gas, but does not
report so.
Likewise, there is a single melting point for carbon, but does not specify for
which polymorph this is: graphite, graphene, buckyball, or diamond.
