TRANSCRIPT
CRITICAL CONSTANTS
The parameters of the liquid–gas critical point are important constants in determining the behavior of fluids. This table lists the critical temperature, pressure, and molar volume, as well as the normal boiling point, for approximately 850 inorganic and organic substances. The properties and their units are:
Tb: Normal boiling point in kelvins at a pressure of 101.325
kPa (1 atmosphere); an “s” following the value indicates a sublimation point (temperature at which the solid is in equilibrium with the gas at a pressure of 101.325 kPa)
Tc: Critical temperature in kelvins
Pc: Critical pressure in megapascals
Vc: Critical molar volume in cm3/mol
The number of digits given for Tb, T
c, and P
c indicates the esti-
mated accuracy of these quantities; however, values of Tc greater
than 750 K may be in error by 10 K or more. Although most Vc
values are given to three figures, they cannot be assumed accurate to better than a few percent. All values are experimentally deter-mined except for a few values, indicated by an asterisk*, which are based on extrapolations. Methods of measurement are described and critiqued in Reference 1.
Many of the critical constants in this table are taken from re-views produced by the IUPAC Commission on Thermodynamics (References 1– 8). Compounds are listed by molecular formula in modified Hill order, with compounds not containing carbon pre-ceding those that do contain carbon.

ENTHALPY OF FUSION
This table lists the molar enthalpy (heat) of fusion, Δfus
H, of over 1100 inorganic and organic compounds. All values refer to the enthalpy change at equilibrium between the liquid phase and the most stable solid phase at the phase transition temperature. Most values of Δ
fusH are given at the normal melting point t
m. However,
a “t” following the entry in the melting point column indicate a triple-point temperature, where the solid, liquid, and gas phases are in equilibrium. Temperatures are given on the ITS-90 scale.
A * following an entry indicates that the value includes the en-thalpy of transition between crystalline phases whose transforma-tion occurs within 1°C of the melting point.
Substances are listed by name, either an IUPAC systematic name or, in the case of drugs and other complex compounds, a common synonym. Inorganic compounds, including metal salts of organic acids, are listed first, followed by organic compounds. The molecular formula in the Hill convention is included.

PRESSURE AND TEMPERATURE DEPENDENCE OF LIQUID DENSITY
This table gives data on the variation of the density of some common liquids with pressure and temperature. The pressure de-pendence is described to first order by the isothermal compress-ibility coefficient κ defined as
κ = -(1/V) (∂V/∂P)T
where V is the volume, and the temperature dependence by the cubic expansion coefficient α,
α = (1/V) (∂V/∂T)P
Substances are listed by molecular formula in the Hill order. More precise data on the variation of density with temperature over a wide temperature range can be found in Reference 1.

milliliter ∆
fusH @ T

THERMAL PROPERTIES OF MERCURY
Lev R. Fokin
The first of these tables gives the molar heat capacity at constant pressure of liquid and gaseous mercury as a function of tempera-ture. To convert to specific heat in units of J/g K, divide these val-ues by 200.59, the atomic weight of mercury.
