Changes in physical state
three states of matter temperature measurement
Three states of matter: solid, liquid and gaseous
temperature measurement
Temperature indicates how hot or cold an object is
Unit of temperature: degrees Celsius (℃)
Tools: Thermometer
Classification
Experimental thermometers, thermometers, thermometers
principle
Thermal expansion and contraction
Instructions
melting and solidification
melt
Definition: A substance changes from a solid state to a liquid state
Features: heat absorption
Crystal (melting point)
Ice, sea waves, various metals
Amorphous
wax, rosin, glass, asphalt
Melting image: reaches the melting point, continues to absorb heat, internal energy increases, and the temperature remains unchanged
solidification
Definition: Substance changes from liquid to solid
Features: heat release
Crystal (freezing point)
Amorphous
Freezing image: When the freezing point is reached, heat continues to be released, the internal energy decreases, and the temperature remains unchanged.
Vaporization and liquefaction
liquefaction
Definition: Substance changes from gaseous to liquid state
Features: heat release
method
Reduce the temperature
Compressed volume
Features: dew, fog, "white steam", etc.
Vaporization
Definition: Substance changes from liquid to gaseous state
Features: heat absorption
Way
evaporation
Cooling and cooling
Influencing factors
liquid temperature
Liquid surface area size
How fast air flows on the surface of a liquid
boiling
condition
reach boiling point
Constantly absorbing heat
The temperature does not change, but it still needs to absorb heat
sublimation and sublimation
sublimation
Definition: Substance changes directly from solid to gaseous state
Features: heat absorption
Typical examples: frozen clothes dry out, etc.; filament becomes thinner; iodine sublimates
Sublime
Definition: Substance changes directly from gaseous state to solid state
Features: heat release
Typical examples: frost, rime, etc.
