Phase Changes Flashcards
(16 cards)
Is the phase change involves a gain
or absorption of heat by the
substance from the environment.
Endothermic
Is the phase change involves a gain
or absorption of heat by the
substance from the environment.
Endothermic
It involves loss or release of heat by
the substance to the environment
Exothermic
Temperature at
which the solid
melts to form a
liquid
Melting Point
Temperature at
which the liquid
starts to boil
Boiling Point
Temperature at
which the liquid
starts to boil
Boiling Point
Is when heat is removed or cooling a
liquid decreases the kinetic energy of
the particles until they are unable to
move and remain in fixed positions.
Freezing Point
Is the process where the particles
escape and enter the vapor or gas
phase above the liquid
Evaporation
● Gas to Liquid
● The reverse process of evaporation
● This happens as particles in the vapor
phase are cooled
Condensation
Change from solid to gas without
passing the liquid state
● Reverse of Deposition
Sublimation
Change from solid to gas without
passing the liquid state
● Reverse of Deposition
Sublimation
Change from gas to solid phase
without passing the liquid phase.
● The reverse of sublimation
Deposition
Change from gas to solid phase
without passing the liquid phase.
● The reverse of sublimation
Deposition
show how the temperature changes
as a substance is heated up.
Heat Curves
show how the temperature changes
as a substance is heated up.
Heat Curves
show how the temperature changes
as a substance is cooled down.
