What is an atom?
200
This state has tightly packed particles that vibrate against eachother and cannot change shape or volume.
What is a solid?
200
A mixture where one substance dissolves into another but can still be separated.
What is a solution?
200
True or False: Rust is an example of a chemical change?

300
How much space matter takes up.
What is volume?
300
The chemical combination of two or more elements.
What is a compound?
300
This state's particles are loosly packed and move at a medium speed allowing it to change shape but not volume.
What is a liquid?
300
This substance does the dissolving in a solution.
What is the solvent?
300
True or False: A chemical change can be reversed.
What is False?

500
The three particles found inside of an atom.
What are protons, electrons and neutrons?
500
The three points that can cause a change of state.
What are melting point, freezing point and boiling point?
