getTDependentProperty

getTDependentProperty is used to retrieve compound specific values that depend only on temperature.

Syntax

value=getTDependentProperty(propName,temperature)

Arguments

propName
String; name of the temperature dependent property. The following temperature dependent properties may be supported, depending on the underlying thermo system:

property namedescriptionunit of measure
cpAqueousInfiniteDilutionHeat capacity of a solute in an infinitely dilute aqueous solutionJ / mol / K
dielectricConstantThe ratio of the capacity of a condenser with a particular substance as dielectric to the capacity of the same condenser with a vacuum for dielectric-
expansivityCoefficient of linear expansion for a solid: (1/L) d L / d T (where L is the length) at 1 atm1 / K
fugacityCoefficientOfVaporFugacity coefficient of vapour on the saturation line-
glassTransitionPressureGlass transition pressurePa
heatCapacityOfLiquidHeat capacity (Cp) of liquid on the saturation lineJ / mol / K

volumeOfSolidVolume of solid at 1 atmm3 / mol
The temperature derivatives of the above properties may be obtained by adding .Dtemperature to the property name, e.g. vaporPressure.Dtemperature

temperature
Double; temperature (K) at which to retrieve the property values

Returns:

value
Double; values for the temperature dependent properties. Return value is a row vector with one element for each compound.
