Answer 9

condensation

Question 10

conditions of pressure and temperature at which a phase is stable

Answer 10

Regions of the diagram

Question 11

TRUE or FALSE: In general, the solid is stable at low temperature
and high pressure, the gas at high temperature
and low pressure, and the liquid at intermediate
conditions.

Answer 11

CHREW

Question 12

• phase transition curve
• Equilibrium exists when two processes that are reversed of each other happen at the same rate.

Answer 12

Lines between regions

Question 13

TRUE or FALSE: Equilibrium is commonly achieved when the system is open, so phase changes found in everyday scenarios usually are not in equilibrium.

Answer 13

FALSE; when the system is closed

Question 14

A point in the diagram where all three phases are in equilibrium.

Answer 14

Triple point

Question 15

al point - A point in the diagram where the densities of the liquid and gas become equal, and the phase boundary disappears.

Answer 15

Critical point

Question 16

TRUE or FALSE: Beyond the critical temperature, a supercritical fluid (SCF) exists rather than separate liquid and gaseous phases.

Answer 16

true

Question 17

They are homogeneous mixtures that appear as one phase

Answer 17

Solutions

Question 18

determines what phase the entire solution will assume

Answer 18

Phase of the Solvent

Question 19

• refers to the point at which a solution contains the maximum amount of solute that can dissolve in a solvent at a specic temperature and pressure.

Answer 19

Saturations

Question 20

maximum amount that dissolves in a xed quantity of a given solvent at a given temperature, when an excess of the solute is present.

Answer 20

solubility

Question 21
