200
When this is added, particles begin to expand and vibrate faster.
What is heat energy?
200
This is the formula for density.

300
Burning a tree is an example of this type of change.
What is a chemical change?
300
Use this number to determine the number of protons in an atom.
What is the atomic number?
300
This phase has definite mass, definite volume, and definite shape.
What is a solid?
300
This is the part of a solution that is usually in greater quantity.
What is the solvent?
300
The phase change from a liquid to a gas.

400
Breaking a ruler is an example of this type of change.
What is a physical change?
400
The number of electrons is always equal to the number of this particle in an atom.
What are protons?
400
This phase has definite volume and mass, but not definite shape.
What is a liquid?
400
This is the part of a solution that is usually in lesser quantity.

500
This phase has definite mass, but does not have definite shape and volume.
What is gas?
500
These three things can affect solubility.
