- to shrink, when the temperature of a substance decreases, its particles slow down and move closer together
- CONTRACTION
- to spread out, when heat is applied to a substance its particles begin to move more rapidly and spread out as they get hotter
- EXPANSION
- the gradual change of a liquid into a gas
- EVAPORATION
- the rapid change of a liquid into a gas that occurs when heat is added
- BOILING
-
retain their shape
volume does not change, regardless of the container it is placed in
not fluid
many form crystals - SOLIDS
-
take on the shape of their container
have a definite volume – they settle to the bottom of the container
fluid - LIQUIDS
-
do not have a fixed volume – the volume is determined by the container
fluid - GAS
- the changing of a gas into a liquid
- CONDENSATION
- the temperature for a specific substance at which it changes from a liquid to a solid
- FREEZING POINT
- the temperature for a specific substance at which it changes from a liquid to a gas
- BOILING POINT
- the temperature for a specific substance at which it changes from a solid to a liquid
- MELTING POINT
- molecules arranged in organized patterns
- SOLID
- when heat is added to a solid the molecules vibrate faster and spread apart, resulting in a __________
- LIQUID
- When even more heat is added the molecules continue to speed up and move further apart, resulting in a ____________
- GAS
- The three states of matter
- SOLID, LIQUID, AND GAS
