Exam 3 Terms Flashcards
A form of matter that is uniform throughout in chemical composition and physical state
Phase
A line that separates the phase of a substance on a phase diagram
Phase boundary
A plot a pure substance that shows different regions of pressure and temperature at which the various phases are thermodynamically stable
Phase diagram
The condition of free vaporization threw out a liquid
Boiling
The temperature at which the vapor pressure of liquid is equal to the external pressure
Boiling temperature
The boiling temperature, when the external pressure is one atm
Normal boiling point
The boiling temperature when the external pressure is one bar
Standard boiling point
The temperature at which the surface of a liquid disappears
Critical temperature
The pressure of a liquid critical temperature
Critical pressure
A single uniform phase of a liquid above the critical temperature
Supercritical fluid
The temperature I was the liquid and solid phase of a substance coexist at equilibrium
Melting/freezing temperature
The freezing temperature when external pressure is one atm
Normal freezing point
The freezing temperature when external pressure is one bar
Standard freezing point
Appointment wish all three phases boundaries (Solid, liquid, gas) meet
Triple point
A physical property that depends on the relative number of solute particles presents but not their chemical identity
Colligative property
