300
These are the particals that are arranged in repeating geometric patterns
What are crystals
300
This is water that contains unwanted materials that make it unacceptable for drinking

300
When a liquid changes to a gas
What is evaporation
300
If you decrease the volume of a container of gas, the pressure will increase, provided the temperature doesn't change
What is Boyle's Law
300
The pressure applied to a fluid is transmitted unchanged throughout the fluid
What is Pascal's principle
400
These are the four states of matter
What is plasma, gas, solid, and liquid

The amount of energy needed to change a solid to a liquid
What is heat of fusion
400
The volume of a gas increases with increasing temperature, provided the pressure doesn't change
What is Charles's Law
400
The buoyant force on an object in a fluid is equal to the weight of the fluid displaced by the object
What is Archimedes principle
500
The most common state of matter is _______
