Phase Transition
|
transformation of a thermodynamic system from one phase or rate of matter to another
|
|
Supercritical Fluid
|
When a pressure and temperature is exerted above a critical point and a distinct liquid or gas phase does not exist
|
|
Critical point
|
Critical temperature and pressure are together and no phase boundaries exist
|
|
Critical pressure
|
Is the vapour pressure at critical temperature where the density of pressure and temperature is equal
|
|
Critical Temperature
|
Temperature at which the surface disappears and there is no longer a boundary between temperature or pressure they are identical
|
|
Triple Point
|
Where all three phases coexist simultaneously
|
|
What is unique about the solid liquid line in water?
|
It has a negative gradient rather than a positive since ice has a lower density due to its open crystal structure of H bonds
|
|
Phase Diagram
|
Map of a substance showing the conditions of temperature and pressure at different phases which are thermodynamically stable
|
|
Phase boundaries
|
Show the values of P and T where the phases are different on either side and a dynamic equilibrium along the line where the forward and backward reaction are occurring at the same rate
|
|
All three phases coexist simultaneously
|
Triple point
