Constructor Summary

Liquid()

Liquid(java.lang.String _label, ChemSystem _chemSystem, ChemSpecies _chemSpecies)
The minimal requirements for defining a Liquid phase are a descriptive label, the chemical system containing the phase, and the chemical species the constitutes the liquid.

Method Summary

Phase	copyOf(ChemSystem _chemSystem) Creates a copy of this phase and places it in the indicated ChemSystem.
Species	getAcid() Returns null, because there is no solvent or conjugate acid in this type of phase.
Species	getBase() Returns null, because there is no solvent or conjugate base in this type of phase.
java.lang.String	getInfo() Returns information about this class
double	getIonicStrength() Returns zero, because ionic strength has no meaning for this phase
double	getMass() Returns the mass in grams of the liquid.
double	getPressure() Returns the pressure of the liquid, which is the same as the system pressure.
Species	getSolvent() Returns null, because this phase has no solvent
double	getVolume() Returns the volume of the phase in liters
void	setDensity(double _density) Sets the density of the liquid.
void	setMass(double _mass) Sets the mass of the liquid.
void	setVolume(double _volume) Sets the volume of the liquid.

Liquid

public Liquid()

Liquid

public Liquid(java.lang.String _label,
              ChemSystem _chemSystem,
              ChemSpecies _chemSpecies)

The minimal requirements for defining a Liquid phase are a descriptive label, the chemical system containing the phase, and the chemical species the constitutes the liquid.

Method Detail

copyOf

public Phase copyOf(ChemSystem _chemSystem)

Creates a copy of this phase and places it in the indicated ChemSystem.

Specified by:

copyOf in class Phase

getInfo

public java.lang.String getInfo()

Returns information about this class

Overrides:

getInfo in class Phase

getAcid

public Species getAcid()

Returns null, because there is no solvent or conjugate acid in this type of phase.

Specified by:

getAcid in class Phase

getBase

public Species getBase()

Returns null, because there is no solvent or conjugate base in this type of phase.

Specified by:

getBase in class Phase

getIonicStrength

public double getIonicStrength()

Returns zero, because ionic strength has no meaning for this phase

Specified by:

getIonicStrength in class Phase

getMass

public double getMass()

Returns the mass in grams of the liquid.

Overrides:

getMass in class Phase

getPressure

public double getPressure()

Returns the pressure of the liquid, which is the same as the system pressure. (This property is NOT the vapor pressure of the liquid.)

Specified by:

getPressure in class Phase

getSolvent

public Species getSolvent()

Returns null, because this phase has no solvent

Specified by:

getSolvent in class Phase

getVolume

public double getVolume()

Returns the volume of the phase in liters

Specified by:

getVolume in class Phase

setDensity

public void setDensity(double _density)

Sets the density of the liquid. The volume of the liquid is adjusted to be consistent with the mass and the density.

Specified by:

setDensity in class Phase

Parameters:

_density - density in grams per milliliter

setMass

public void setMass(double _mass)

Sets the mass of the liquid. The volume of the liquid is adjusted to be consistent with the mass and density.

Specified by:

setMass in class Phase

Parameters:

_mass - mass in grams

setVolume

public void setVolume(double _volume)

Sets the volume of the liquid. The density is used to calculate a new mass for the liquid.

Specified by:

setVolume in class Phase

Parameters:

_volume - volume in liters
