States of Matter
The three most familiar states of matter
What are solid, liquid, and gas?
Definition of Kinetic Energy
What is the energy of motion / movement?
When a liquid changes to a gas
What is evaporation?
When matter changes from liquid to solid.
What is freezing?
These are the 2 main categories of matter
What are pure substances and mixtures?
The addition of removal of this causes phase changes
What is energy / heat?
When a liquid changes to a solid
What is freezing?
When matter changes from a solid to a liquid
What is melting?
The phase change that occurs when a chocolate bar is left in a hot car
What is melting (solid to liquid)?
This state of matter has particles with the lowest average kinetic energy
What is solid?
This term describes a process in which heat is added to the system
Warming
When matter changes from gas to liquid
Condensation
This phase change occurs when sweetened cream is turned into ice cream
What is freezing (liquid to solid)?
This state of matter has particles with the highest average kinetic energy
What is gas?
This is the term for two or more substances together that do not bond to form a new substance
What is a mixture?
When matter changes from gas to solid (skips the liquid phase)
Deposition
This phase change occurs when rain clouds form in the atmosphere
What is condensation (gas to liquid)?
This is the 4th possible state of matter
What is plasma
As temperature increases, this happens to the motion of molecules (2 parts)
What is molecules speed up and spread out?
This type of matter takes the shape of its container but has a definite volume
What is liquid?
When matter changes from solid to gas (skips the liquid phase)
Sublimation
This phase change occurs when dry ice turns into carbon dioxide gas
What is sublimation (solid to gas)?
