Changes in physical state
concept
Different states of matter existing at different temperatures and pressures
solid state
Matter has a fixed volume and shape
Typical examples: ice cubes, diamonds
liquid
Matter has a fixed volume but a variable shape
Typical examples: water, oil
gaseous
Matter has no fixed volume or shape
Typical examples: air, water vapor
physical state change process
melt
The process by which a solid substance absorbs heat and converts into a liquid state
Typical example: Ice cubes melt into water
solidification
The process by which liquid substances release heat and convert into a solid state
Typical example: water freezes
Vaporization
The process by which a liquid substance absorbs heat and converts into a gaseous state
Typical example: water evaporates into water vapor
liquefaction
The process by which gaseous substances release heat and become liquid
Typical example: water vapor turns into small water droplets when cooled
sublimation
The process in which solid matter absorbs heat and is directly converted into a gaseous state
Typical example: Dry ice sublimates into carbon dioxide gas
Sublime
The process in which gaseous substances release heat and are directly converted into solid state
Typical example: water vapor turns into frost when cooled
Influencing factors
temperature
The higher the temperature, the easier it is for substances to undergo changes in physical state
pressure
The higher the pressure, the more difficult it is for a substance to change state.
Substance type
Different substances have different melting points, boiling points and other characteristics, which affect their physical state change process
application
Application in daily life
Using the phenomenon of melting to make ice cream
Using the phenomenon of vaporization to make a steam iron
Applications in industry
Harnessing the phenomenon of melting to create metal parts
Make use of vaporization phenomenon to make refrigeration equipment;
